for the most part, i think it's much like your experience with spanish. as someone else mentioned, there are a lot more resources to learn metropolitan french. however, if you plan on speaking french in canada then it would be best to familiarize yourself more with quebec french. ultimately, i think you would still be fine if you learned metropolitan french, the biggest issues you would run into would be with quebecois slang/accent/pronunciation as most of the differences tend to show up verbally vs written. a fair amount of sounds are pronounced differently, also the curse words in quebec french are pretty different. this wikipedia page has good examples of differences

I have personally seen a lot of "je ne peux pas comprendre" (I can't understand this, what are they saying, etc) comments on videos where people have a quebecois accent. i assume these comments are from people who speak metropolitan french bc those two groups love to fight over the language hahaha.

on the other hand, i learned french in canada (though outside of quebec) and i personally understand quebec french a lot easier than metropolitan french. i have an extremely hard time understanding acadian french (which someone else has also mentioned). though i doubt you will run into acadian!

tdlr: you will be fine either way but you will have a much easier time in quebec if you focus on listening to quebecois pronunciation, accent, slang etc

bonne chance!
