One other option is the “Always Free” tier on Oracle Cloud. You get some potato EPYC instances and some Altera ARM ones that are quite nice.
There are people who have issues with their accounts getting banned with no recourse, but I’ve used OCI free for over a year with no issues (and run a Mastodon instance on some of the ARM stuff), and know a good number of people who have various services running on it with no issue long-term, so YMMV.
The price is right, though, and you should keep current backups regardless.
