The Linux Foundation has a mentorship programme which is really great, might be worth a look, although I am not sure how easy it is to get accepted: https://docs.linuxfoundation.org/lfx/mentorship/mentees
If you are open to building something yourself this might be an alternative (disclaimer: I just know of this project but no idea how well it works): https://www.findmycat.io/

You should be able to connect to the Chromecasts setup hotspot, get the IP of the Chromecast and then run the script.

The most important thing, if you intend to do outgoing email, is to get a reputable hosting service, where you'd have few/none bad neighbours. Unfortunately that often doesn't come together with cheap, as cheap solutions often attract a certain clientele. I've also had more luck with slightly smaller (but still reputable) providers, i.e stay away from OVH / Hetzner and the like. If you want something cheap, it'd probably not be a good experience to self-host.

LXD is really a great project (when run without snap...), in large part due to Stéphane. This is a real shame.
Delta is great! Only thing I found a bit inconvenient is that the output is a bit less shareable as it relies a lot on colors. For example if one wants to copy a few lines of a diff to someone on slack.
