There is an inherent catch-22 in that the people who believe AI a fluke will rarely have the time/interest in realizing the vast improvements since the initial launch 2-3 years ago.
I am as frugal as they come, yet I shell out money for the paid version and have a reference point on its helpfulness that is grounded in experience. It is almost impossible trying to create a reference point to those that have no (recent) experience and refuse to get any.

One suggestion is to look at getting any useful docker container up and running first to get a feel for it, then pivot towards heavier lifts. Self-hosting emails is going to be a headache as others have said, and monero nodes sounds like it could be a technical as well but that’s admittedly an uneducated guess.
You can look at the recent selfh.st poll for the most popular docker containers, see if any strike your interest and start there.
