iSH is free and you can download it from the AppStore, it’s kinda sluggish because it’s Alpine Linux x86, but you can run a lot of shell utilities
For the last: UTM + JIT. Unfortunately it’s not on the AppStore, but those utilities will allow you to run any operating system (that doesn’t mean they’ll be useable). I use Debian ARM64 (with LXQt environment) on my iPad mini (A12) which runs fast enough to handle sublime text and one terminal window (but not a web browser ;_;). Some software won’t run on it like PSEint (unless you figure out how to compile it), but it’s faster than iSH and has more software compatibility than a-shell
