Yet another crypto cashout with almost non SoF?

Hi, new member here.

Brief history...

A friend showed me bitcoin in 2011 and we sent coins back and forth, mined and played around with them on websites that were announced on bitcointalk.

FOMO kicked in at the end of 2012 and I bought as many coins as I could afford in early to mid-2013.

At the end of 2013, the playing around and the small investment started to turn into a nice sum. And so I created a new address, created several backups, and send all my btc via the blockchain.info wallet mixer there. That's the oldest address I still own and which I used for buying altcoins over the years.

I made my first withdrawal a few years later. At that time SoF was just a meeting at my local bank branch and a rough excel document via email, as many exchanges no longer existed and I could only give rough information about SoF. The purchases in 2013 went through my bank account, so they were able to trace them. But these were only ~1/3 of my coins I have owned at one point. After a few weeks there was an ok and the payout process ran without problems since then.
I also had to (re)pay taxes for one year.

I have paid out a few times since then, always just what I needed.

Last year my exchange blocked my btc deposit. I was able to access them again after around 1 week and could sell them but there was a timely termination.
I guess the risk analysis of the coins sent there was too high?

After reading a bit more about SoF/SoW and also stumbling across possible horror scenarios, I no longer dared to cash out at another exchange, as I am missing most of the SoF from 2011 to 2013. And in some cases I am also missing some trades beyond that, although I was able to reconstruct them at least roughly, some even completely.
And I have no desire for a possible (further?) suspicious activity report to the FIU. I also don't like the idea of sending SoF to exchanges which are constantly being hacked and only lose user data anyway.
I value my privacy as much as possible in this surveillance-obsessed world. On the other hand, of course, I want to access my money.

What options do I have to access my money (legally)?
Do I have to leave Ursula-State at some point?
Can anyone help me?

I cashed out person to person a few times, works fine. But some issues:

1. I'm death way before I spent this amount of coins in cash or crypto cards - even if I no longer lead a very modest life. Also good chance that cash won't even exist for that long anymore.
2. I need at least some bank money to live, cash/CC alone doesn't work here for everything.
3. As said in other thread: tell me CC service which will accept old and (most likely - I don't know) tainted coins. Because if someone asks about SoF, I'll be able to explain roughly what I did with my coins, but it won't be 100% clear/verifiable.
4. I have/want to buy me another car and/or house at some point - nothing fancy, but after all, it's my money.
5. Lawyers strongly advised against continuing to cash out person to person for cash, at least if it's more than 500 Euro - because it seems that nowaday everything can be interpreted as money laundering. And 500 Eur is ridiculously low to meet with anyone at all.

Sadly lawyers say: just try to cash out via other regulated exchange, if it does go wrong, just get in touch again lol. Very unsatisfied answer, which did not really take away my fear after last year, where my deposit on a regulated exchange triggered an automatic blocking of funds and they canceled my account. This is how/why I ended up here.

Can you name some services for crypto cards and OTC desks?
Do both of them don't need SoF? because if someone asks for SoF (my coins are most likely tainted to some extend, so could trigger chain analysis), I'll be able to explain roughly what I did with my coins, but it won't be 100% clear/verifiable and as far as I know that could lead to report to FIU nowadays. Maybe even confiscation I don't know. And I'm pretty scared about all of these unnecessary regulations and my situation - maybe I'm overreacting, but I can't tell.

Oh, maybe my text wasn't clear enough. I don't hold coins on an exchange. I just want to sell some here and there again.
But I'm afraid that I won't be able to find a new exchange with my SoF issue or that I will inevitably be reported to the FIU from an exchange due to incomplete and difficult/impossible to trace documentation as soon as I have to send documentation to them (as I tried to explain in my first post).
And I'm also not sure if OTC desks will help here - something like Clarity Global (mentioned by Bruce flea) states on their website faq that they need SoF too - not to mention that the service only seems to be available for registered business.
As you can guess, I have absolutely no idea about the whole legal topic.
