Hmp. All that said...
I think I'll wait a week and play around with stuff and see how the technical difficulties shake out.

Oh! I just noticed that the current Mastodon version puts links to lists in the right sidebar! And Misskey is not too bad, remembering at least the last list you used... That's nice and takes a bit of the weight off the Lists pro for Friendica...

additional Friendica con: Need to get used to it, in particular how it handles CWs.

my own friendica node
pro:
- my thing. not relying on a third party.
- lists feature that is Right There, i.e. the first one I've seen I'd use.
- "bookmark" posts in folders
- might have good integration with Twitter and possibly tumblr?
con:
- Worst emoji support. Really bad. No customs.
- I can't get it to federate with ping.the-planet.space, which is really bad because that's where some of my best friends are.
- I have to actually keep up with admin stuff, like keeping an eye on disc usage.

mastodon.art
pro:
- mastodon is what I'm used to, no need to get used to much in the way of changes.
- local timeline full or artists!
- someone else administers it
con:
- no blobcat emojis :(
