Let's say I have this string:
[section][module_text id="123"]text[/module][module_number id=""]000[/module][/section]
I can find each entire [module...[/module...] substring with
([module)(.*?)([/module.*?])
But I would like to only match the [module] string that has a digit in the id="" parameter. In this case the first [module].
I've been trying a bunch of stuff but i cant seem to get any closer.

After matching module, you can match non-] characters until you get to the id part, and after the id's ", you can match [^"]*d to ensure that the id has a digit in it:
([module[^]]*id="[^"]*d)(.*?)([/module[^]]*])
https://regex101.com/r/25JcEP/1
If the modules you want to match have ids which always start with digits, then you can simplify it a bit to
([module[^]]*id="d)(.*?)([/module[^]]*])
Note the use of a negative character class rather than .*? for the final ([/module[^]]*]) - negative character classes are a bit more efficient than lazy repetition when possible.
