So for this I am maybe too paranoid, but it is an interesting discussion. Do you have more information on your wireless wind sensor? I am curious as I have a design as well. For this i would use asa too, but seal the electronics in potting compound.
You are not paranoid. Its good to be waterproof as much as you can. But after some point it is not worth it. Especially for the wind sensor. It will be on top of the mast so not so much saltwater as down.
You can find the project in my repo on github. Its originated from Norbert Walters yachta project. I changed the pcb a little bit to fit a bme280 sensor. Altered the cad files also a little bit so it fits the sensor and be a little bit more protected from rain. Finally i made quite a few changes in the firmware.
Its a very good design. I installed SS bearings and screws. Only the bearing at the cups is ceramic because it the most exposed. All bearings of course are aliexpress grade.
When i have some time i want to improve it a bit but its not on top of my list because it works like it is.

I forgot to include the presentation video. Unfortunately it is in Greek. Maybe it has some youtube auto translation. I dont know..
