ultimately you either go properly ND/Baptist or you go Catholic.
Orthodox is valid only when your nation basically rigs it that if you went Cath you can't marry an Ortho and your nearest Cath church is 4 towns away and just not worth it.
In such scenario God will forgive you not having a true seal-guaranteed confessional process. You can use the seal-not-guaranteed confessional for most sins and any too risky/taboo God will forgive because in that nation you prioritised assimilation to their Christianity and tried your best.
At least they try their best to be true Christians (and Russia's actually is the single worst out of the EO at this so idk why you chose them, furthermore if you're anti-Islam to that degree, you shoul dbe aware that Russia is the only EO nation that has literally harsh enforced blasphemy laws that it applies to thos ethat speak against Islam just as harshly as to those that speak against Christianity (yes, the religions, not the people alone it actually probably goes less harsh on racism than anti theism).
You are Lutheran, big deal. You think Nordic model can be anything by heavily secularised and agnostic/atheistic to the hilt, big deal. The actual Lutheran OG cultures have proven exactly what Lutheranism leads to, you're trying to compensate by making it as Catholic-Mass as possible without being Catholic and you're only focused on the Mass, ignoring the works and actual serving of God that matter far more than some damn bread on your tongue. Even Catholics who are very serious, know that works matter a lot. That is actually why you must not take Eucharist if your works were too terrible and you haven't yet been absolved as per Catholic doctrine.
I don't dislike Confessional Lutheranism, it's better than the stuff the generic Lutheranism does. What you will realise in the debate is that Luther would not at all give a damn about them and that modern Baptists are actually a lot closer to Luther's approach, you just have it wrong. Modern Baptists who are not heavy on the added solas (PotS etc) push the angle Luther did more strong than even confessional Lutherans do. They actually live out the Sola Fide and Sola Scriptura approach significantly more because to them that bread is just another physical works-like or pagan-like concept they deny outright as they're very literalist about that stuff. They're also wither happy clappy liberal types (I don't dislike their love and joy for God and music unlike a hard trad cath but I do think they are barely trying to submit to God) or they're the ultra abstinence (even from alcohol etc) types that believe in some rigid sort of application of rules that Paul actually preached against.
The reality is that the only reason Confessional Lutherans are good Christians potentially, is that they can end up mimicking Catholic approach enough that they probably do end up being decent Christians. That's the cold hard truth.
Pope Leo is starting now to go the Pope Francis route a little too much. He's said Anglicans and Catholics are "are already one". This double speak politically correct stuff is not my style but my style likely would cause major upheaval. The reality is that you can keep pushing what you want.
You either are an ND and your denomination basically is just a means to an end to have a community and take the bread/wine if that means a lot to you or you're one of the OG churches that have apostolic succession and proper eucharistic approach (orthodox do have proper eucharistic approach and do have an arguably valid apostolic succession).
You already conceded bit by bit every single thing I opposed you on earlier. The main disagreement you and I have is about the Catholic Church and its approach. That will be the hugest clash in the debate.
You believe a Catholic that's quietly slightly heretical is immediately to be excommed and thus should opt for Lutheranism (I predict). Whereas I believe that a Lutheran who wants confession to a Priest and the other stuff should be Catholic (your Priests are basically just Pastors btw, cosplaying as valid clergy I am not saying this to be cruel but you need to realise the actual way the Catholic Church sees your Clergy to realise the issue with confessing to that 'Priest'). You have every right to be a Lutheran and a Christian. You can be one that stamps your foot down, screams to the wind about how great Lutheranism is and all of this. You will find over time that you only can justify Lutheranism when it more and more mimics Catholicism. So the reality is, what I was saying this paragraph's start is that you see a Catholic who slightly heresies and leans Lutheran on some things (like you know Caths these days often are to some degree in Europe at least), or you can decide it's that huge of an issue and stay Lutheran.
Just remember, your Lutheran priest's 'seal of confession' is about as secure as a chat with anyone else at basically any time. It's not even close to doctor nor lawyer level confidentiality. A Catholic Priest's is. That's a huge difference already with the level of trust you can have. Also realise that because it's entirely optional to Lutherans as opposed to 'maybe optional in a technical way but you definitely are supposed to do it' as modern Catholicism sees it, that your Lutheran Priest is going to be annoyed if you go too often (which probably means going more than twice in 4 months). In contrast, a Catholic Priest would begin to get annoyed if you consistently went let's say every week or 2 weeks again and again especially for the same sins. The Priest wouldn't be annoyed at your neediness to have it alone, just at maybe needing to make time for it or in that scenario that you seem unrepentant and are treating it like a 'soothing session' and taking advantage of pastoral care duties vs truly submitting and serving the Lord.
You can do what you want. You can keep believing what you want. I also am pretty sure it's a lot easier to become a Lutheran Priest than a Catholic Priest. LGBTQ (maybe not T but LGB openly) and female Lutheran Priests already operate in Scandinavia and some parts of Germany. It's a matter of time before you will see that happen to your American Lutheranism, confessional or not.
