Im a first-gen bride and Im lost lost! Any tips for wedding planning ? Anything helps!! Tia!!!

So me (20f) and my fiance (22m) are hoping for a summer 2021 (but with covid Idk for sure yet) wedding, but I have never attended a wedding or planned one, and I dont know anyone who has. Everytime I go on Pinterest or Google I get so overwhelmed.. I wish I had someone to ask for advice but I dont lol my mom married my dad in her grannys living room while wearing a Led Zeppelin T shirt. I dont want a Kardashian style wedding or anything, but I would like it to be a special day as Ive never really had anything like that (no grad party, no bday party, no prom etc)..

The only thing I know I wanna do for sure is have the ceremony and reception at my fiance's mom's coffee shop. Its big and beautiful and far enough away to where any of my family that I don't want coming (most of them lol) probably wont even bother trying to make the trip. Also I want it to be 100% alcohol free and kid friendly. Thinking maybe an open espresso bar rather than an alcohol bar? Idk, again Im so naive with all of this so maybe thats irrational ? Thank you to anyone responding with any tips, lists, recommendations etc!!!
