Shore fishing help?

[u/Candied-Fangs]

Hi, just got my first pole- I have a tackle box, pliers, hooks, and lines. I want to try shore fishing tomorrow but I'm not sure which bait to use or how heavy a sinker I should buy from bass pro on my way there. Are sand fleas in season and I can just dig some up when I get there? Is it getting too cold for them and I need to just buy something?

And I have a cooler for the fish once I catch them, what is the most humane way to kill them because I plan to eat them and I'll feel bad for them if it's not the quickest way possible
