I had the same concerns as the OP. I sold my 2019 16" and 2020 13" MBPs and replaced them with a MB Air M1 for now. I got good prices for both. And as a bonus no more fan noise in a much more responsive system.
If the rumored 14" with a more powerful M1 or M2 SOC and Mini-LED display appears next year I will likely get one of those also.
