Correct. You could even start with PHP 7.4 if you're using Bootstrap, and probably not have many issues. Your big hurdle is going to be the PHP 8.x versions. The documentation will help, many common issues are discussed.

Not to muddy the waters but good info to know....

IF you start with 7.4 (I would do that myself), keep in mind that any code designed to run on 8.2 may use PHP code that will fail under 7.4. So, if the mod is strictly for newer versions of Zen Cart, it might contain PHP 8.2 code that will fail in a 7.4-run site. Array is an example of PHP changed in 8.2 that will not work with 7.4.

You have to look both directions when something fails.
