Considering getting the S10e or the Zenfone 10, is there anything I should know or be aware of when looking as s10e listings?

Like are there specific models (I know there's the SM-G970F, SM-G970U, SM-G970W, SM-G9700, SM-G970U1, SM-G970N, SM-G970X etc) that won't work as well with specific carriers or in specific regions?

I'm in the US and use t-mobile, and I'm specifically wanting a prism white s10e with the 256gb internal storage

(i'm a bit concerned about the s10e's age and lack of security updates and would prefer a zenfone 10, but it's hard for me to find a 512gb US model that's not 500$-600$, if not more)
