I chose to go with #Hollo over other choices because it fulfilled my needs:
I wanted high compatibility with the mastodon API since many of my blogs use mastodon as a comments engine.
It was built for single-user instances (should be relatively lightweight) but also allows multiple accounts for easy separation of topics/posts
It installs with a docker container, which is easy enough if you can follow some instructions and troubleshoot the configuration files with some help (like a technical-minded friend or google gemini)
Related to 3, I can use any server hosting provider, not just managed hosting.
