I need to buy a multimeter. I noticed that for the resistance some

Which one is better to have? Or does it even matter? I'm mostly
interested in testing something that's around 2M. So I don't know if
it matters which multimeter I get.

For resistance measurements, more is better. A short circuit is ideally
zero ohms, and it goes up from there.

Practically speaking, you might never need to measure more than 2
MegOhms, which is a high enough value for most uses.

You're confusing the *resistance* range of a meter to its *impedance*.
Both are measured in ohms. The impedance has nothing to do with how high a
resistance the meter will measure.

No, the OPs question is concerning the upper limit in resistance
measurements, *not* the meter's impedence.

I think you might want to reconsider who is confused here.
