From what I read, you want one with longevity. I would steer clear of the lower ones. 3060, although 12gb of ram, performs on par with 2080 cards. 3060 TI and 3070s are locked at 8 GB of ram, which is likely not going to be enough in the future. 3080 only have 10 GB of ram, which also may not be enough. I know I get capped at some games with my 3070. Granted, it's maxed out graphics @ 1440p, but if thats what you want you're gonna want more VRAM.
I would seriously recommend either waiting to splurge on a higher-end gpu, or if you're in a rush, get an AMD card. I say this as a certified AMD hater, but in the long run the added VRAM will make a difference.
