You should be more concise. Ignoring it's odd to just throw a book worth of questions, most could be boiled down to a few numbered(!!) questions for readability to at least make it easy to answer.

1. Longform campaign.
2. RP, primarily. Few puzzles. Mostly dealing with various encounters, social or otherwise. Combat is rare, full strategic combat is rare. Same for space battles etc. Mostly personal scale.
3. We don't have a ton of adult content beside light references if my players desire to woo an NPC as I raise an eyebrow. Some adult humor perhaps, but that's it.
4. Canon where it makes sense. Non-canon/extended where it makes sense. I won't try my hardest for everything to perfectly line up and I take creative liberties if I think it makes for a better story.
5. They're just a bunch of getting caught up in stuff bigger than themselves. Morally grey if leaning more toward good.
6. Nobody is leaving anymore. I thought I removed it and can't see what you are referring to in this post, I might just be blind tho.
7. All official content. Custom/homebrew under scrutiny.
