If those aren’t burned I to the video, ie you can turn them off, then they must be some magical subtitle format that I’m not aware of.

More or less. Think of it like screen recording the YouTube video as its playing with the subtitles instead of downloading the video.

Two ideas:

1. Get the subtitles burned into the video. Hopefully this will preserve the styling but you’ll loose the ability to disable or control the subtitles after the fact.
2. Download the subtitles as a separate file and configure them to be displayed the same way after the fact. This means figuring out their colors yourself etc. Hopefully you can save those defaults to subtitle file, depending on the format. Most subtitle formats are plain text, so there might just be some metadata field you enter at the top.

All just speculation though. I don’t actually know subtitle file formats etc.

1. What kind of block is it? If its a cloudflare captcha you can use flaresolverr.
2. What is MAM?

Check the memory usage of your rbpi because it should be barely scraping by if you have the max 8gigs. Too many jellyfin sessions open and you might be running into real problems.

Jacket and Prowlarr are redundant. I’d stick with Prowlarr. Also i never heard of Real Debrid before but it sounds redundant to the entire setup.
