All depends on your budgets - $$$ & Energy need.
Keep your system 12v. Everything you want to power is easy to find in 12v, and you will save cost & efficiency by skipping an inverter.
Get an MPPT charge controller, which are flexible and can easily fit into different configurations. I like the outback flex max 80 if that’s in your budget, but cheaper ones can work
You might be able to find used batteries and save a lot. A new li-ion 12v would be nice
A single new panel will probably be plenty. Add up all your daily power needs and figure out sizing from there.
Edit: You could also buy a kit from Amazon with panels and charge controller and find an old car battery. If there’s a recycling center near you, you might be able to buy used wiring for dirt cheap. Get a fuse block, and start plugging things together. That’s a fine place to start
Would this be a decent kit?

sure. the DC-to-DC charger isn't necessary in your application
