What microSD Card and MSPD adaptor should I get?

Since I have a 'brain deficiency' for not wanting to get CFW in 2026, as a Redditor rudely and rather uncalled-for pointed out yesterday, I looked at prices for microSD cards and they are a bit high.

I looked up SanDisk Extreme cards at 30-50€ a pop, ranging from 32 GB to 128 GB. Now the issue is, is there a meaningful difference between Ultra and Extreme cards?

I also looked up adaptors online and I have two possible candidates, but only one of the two states it can work, but only up to 32 GB. The other one has no description besides the boilerplate 'Works for PSP'. The adaptors themselves are pretty okay price-wise at 5-7€, however the memory cards are where I am torn. Performance-wise, which one's best?

And is a 32 GB Ultra SanDisk microSD card going to work? I'm not particularly looking to stuff 160 games onto it; there are only two I am heavily interested in.
