Here are some of the possibilities:
-Star Trek: Strange New Worlds - Season 2. This one is a definite for me even if no one else is interested. I love this series, and this season was particularly well done--so much so that I am concerned about them being able to continue this level of quality.
-Star Trek: Picard - Season 3. Despite being released one episode per week, this show was made to be binged. It's reunion of the Next Generation cast was exactly what I wanted even if the show makes a few missteps. Don't worry if you haven't seen the first two seasons; they have almost no relevance to this third one (which was one of the missteps).
-The Last of Us. I'm less in the mood to watch this in a marathon setting as we rewatched it about a month ago. Still, it's a great series, and I would be willing to watch it with people interested in seeing it.
-Marvel Phase Four and a bit of Phase Five. This gets messy because of the TV shows, but I would at least like to watch the movies again, starting with Spider-Man: Far from Home (technically Phase Three) and all the way to The Marvels. I don't know if I would watch the Eternals again. I think that it at least deserves a second viewing.
-Guardians of the Galaxy. Even though the third movie falls into the above marathon idea, I would like to see the entire story arc for the Guardians (including Avengers 3 & 4 and part of Thor 4).
-She Hulk. I might have to watch this one on my own, but I really enjoyed it and have been wanting to see it again.
-Loki - Seasons 1 and 2. I preferred season 1, but my sons seem to like season 2 more. Both of them deserve another viewing, and likely before the Deadpool and Wolverine movie comes out this summer.
-Which leads to Deadpool 1 and 2. There's only one Marvel movie coming out this year, and it's focused on the Merc-with-a-Mouth. I plan on watching the two theatrical versions (the second movie has three versions) before the movie arrives on July 26th.
Yep. That's a lot of options, and I didn't even list all of them--just the more likely ones.
