I have a few things:

UnRaid server:

• Guacamole (though not really doing anything with it at the moment.)
• Wireguard VPN
• SpeedTest (forget the exact name, does period speed tests and lets me see over time how my connection is doing.)
• DuckDNS
• Heimdall

VM server (esxi 6):

• Windows machine for those times when you just need something
• pi hole
• sharing VM. Dockerized all of the *arrs, sabnzbd, qbittorrent
• plex server. This will probably eventually move off its own VM, but it's there for legacy/laziness reasons.
• Minecraft server, though this is getting dusty as my kids aren't into it like they used to be.

Dell Wyse thin client:

• Home assistant

Pretty simple. I still use iCloud services for most of the other basics (email, call, contacts, iCloud Drive, etc) mostly just because I don't trust my home connection enough to rely on it, and I'd rather the things that actually effect whether or not I can work aren't my problem.
