Need to update, which one?

We have had a eero 6 for years and it’s time to upgrade. We are now receiving 1200mbs so the 6 is good up to 500. I’m thinking the 6+ which will take 1000mbs.

Would it be worth it to buy above the 6+? Like the 6e which can go up to 2.3 gbps? Or would that be a waste since my internet is 1200.
