You also mentioned you're using Apple Remote Desktop - you can do bulk CLI commands and do OS updates via softwareupdate commands. You could make groups and schedule too - half on demand, half a day later. You get the idea.

To be honest, assuming your management is mostly for OS updates and brew/npm, if I were in your shoes, I'd keep going with just ARD. Most MDMs (e.g. Jamf) are a really big job in and of themselves.
