Memory card(s) for G9

I'm sure this has been covered but a quick search didn't yield quite the answers I hoped for so would be grateful for any advice. I'm on the verge of buying a used G9 for 799€ and trying to calculate total cost including necessary accessories such as spare batteries and memory cards. I'd rather not pay more than 50€/card though I guess I don't need to buy two cards just because I have two slots.

I've tried to read up on card specs but am still a bit confused. Anyway I found a card on offer for 40€ that seems to have quite high specs and looks like it should be sufficient, maybe even overkill for my needs. I haven't ever shot long fast bursts and only little video but that doesn't mean I might not want to take advantage of the G9's capacities in the future and the 6K mode looks interesting.

The card is a Lexar Professional SDXC 250MB/s XCII V60 U3 C10 . How would you experts rate it? For comparison I might mention a Sandisk Extreme 150MB/s XCI V30 U3 C10 for 19€ which I guess just might be sufficient(?) but saving (2x?)21€ and then run into speed limits or just not taking advantage of the G9's potential doesn't sound very clever. Both are 64GB. Never came close to filling that on my GX7.

I am no expert, but I purchased the 256GB version of this card for my E-M5 III during a short promotion, to replace my dead SanDisk Extreme Pro:

Lexar Professional 1667x 256GB

Here is the benchmark with CrystalDiskMark on a HyperDrive Gen2 6-port:

This card is a low-cost (and slower) UHS-II, but still faster than any UHS-I card. Thus IMO this card is better if the price are similar to UHS-I.

This is the first Lexar Professional card that I purchased, and I am yet to experience any issues with this card. YMMV though. In real life, this is about 0.5 sec faster for writing each RAW image I take.

Please note that for SanDisk Extreme, the so-called "150MB/sec" transfer speed is limited to their UHS-I card readers. For other devices, the transfer speeds are about 90MB/sec read and 70-80MB/sec write.

I do suggest buying 2 UHS-I cards if the price each is half of Lexar, since I think redundancy is always more important than being just a bit faster.
