Designing a radio frequency PCB with wireless communication
I would suggest your first (or even your first few) PCBs designs not be RF PCBs. An RF PCB one where the RF is actually running through the traces on the PCB you design. Use a radio module instead and mount that to your PCB. That's why they exist.

In RF, everything matters...which is kind of a problem when your hands will be full learning new things without having to worry about RF.

Not only that, it sounds like you will be juggling a microcontroller as well. It's definitely a recipe for failure to try and juggle learning two things (general PCB and microcontroller), and then a third thing that's affected by everything. Just general PCB design or the microcontroller on its own is more than two handfuls already.
