/e/OS at least has a browser based installer[0] for quite some supported phones. I definitely recommend trying it out, installing a custom os on my phone gave me the same feeling when I first ran debian on a laptop struggling under windows (even though the performance gains aren't that apparent in my opinion).
The /e/OS installer is terrible though and often fails, even on their officially supported phones (like Fairphone). The standard recommendation in their forums is nah, just install /e/OS through the command-line.
Also, /e/OS has pretty bad security practices (shipping very old kernels, very old vendor firmware, and missing most AOSP security patches).
Also, be careful to follow the instructions really carefully. For some devices it's really easy to get the phone in a boot loop, where the only resort is to get your vendor to repair it. E.g. Fairphone 6 has downgrade protection and will become a brick if you relocked the phone when the old system's Android SPL is newer than the new system's.
