Late to the party and after reading through some of these setups I may have to expand mine soon (it never ends does it?), here is what I have right now.

There are some other things floating around in my homelab that aren't really 'selfhosted' things, just important to the home network:
3 HP Microserver Gen8's
-x1 with ESXi hosting pfSense
-x2 with TrueNas Scale for backups
R610 with ESXi for a few remote desktops and Home Assistant (which I'm sure I'll move to docker at some point).
A lot of companies are implementing better VPN tech (like SD-WAN, Nebula by Slack, etc), or at the least Microsoft Intune to ensure your corporate laptop is reachable anytime it's connected to the internet.
