Question about gems for armor/jewelry

Hello. I would like to know what will be the best choice of gems for armor pieces and for jewelry in my situation.
Currently I’m planning to run some regular genesis and tempest expeditions(as a tank, 600gs) to learn the mechanics. I would also like to know what to do in the future when I progress to mutations. Should I keep switching gems depending on current weekly mutations, should I buy multiple shields/amulets with resistances against them, or are there other things I should(or shouldn’t) do?
I tried to find information on the internet and I also asked in game but I’m still not sure what to use because there are different opinions on this and trying to find information in old guides may be a bad idea because the game gets updated and things change.
Thanks in advance for any answers.
