https://www.lkhpd.com.sg/cat6a/In this article, we will also explore why Cat 6A took over previous categories (Cat 5, Cat 5e, Cat 6) and why it’s a better option than – theoretically superior – copper cabling types such as Cat 7, Cat 7A and even Cat 8.
Although Cat 6A first appeared in 2004 in the form of CommScope’s SYSTIMAX® GigaSPEED® X10D, it would not be formally published as a standard until 2009. By then, however, it was known across the industry as the cabling category of the future that would enable the next wave of high-bandwidth copper connectivity. This was why cabling manufacturers quickly tried to replicate it and standards bodies were compelled to publish an agreed standard.
Looking back, we see that it has enabled the development and deployment of many bandwidth-hungry applications that today’s enterprises cannot do without. And it is not finished yet – it remains the recommended infrastructure for modern new-builds and promises to remain relevant for many years to come. Proof of its success can be seen in the sales volume that continues to grow, almost two decades after the initial draft of the standard.

recently i myself bought some cat6a after doing my own research. my mistake for my previous purchase was buying a flat cat7 cable. u should go for cat6a rounded cables becauz it's rated for 10gbe, and pricing wise it isn't much more than cat5/cat6, so why not.
another thing u should check is the seller comments, cauz not all cables are equal. the ones i got didn't have complaints on the reliability of the cable, so i felt comfortable buying it.
for 2.5gbe, i think i read they said cat5e would be the bare minimum, also cat6 may work for 10gbe at close distances. but since cat6a isn't that much more expensive, i could justify going cheap here for getting some new ethernet cables for my planned network upgrade.
TLDR
hope that helped, for anyone planning to get any ethernet cables for 2022
