For anyone looking at budget android phones, probably the most important thing is to look at the CPU on gsmarena (or elsewhere) and make sure it has at least 2 a7N cores (the higher the N, the better, eg. a72<a78<a720), because android OEMs are still selling phones with 8 a53 (or a55) cores which are unusably slow (8x a53 cpus were terrible a decade ago, and they're even worse now). For qualcomm cpus you might have to check the wikipedia article [1] to figure out what the kryo cores actually correspond to.
