Shorts and bare legs. If the rain is really cold, then I put this on. It is just one manufacturer's model; there are others.
And ya can't beat that price, either.I only hike in pants, so in heavy rain even silpants can get soaked through. I do as @davebugg does - a rain kilt - except mine is about 20g lighter! I'm not good at linking but yu can find it on Amazon here: 3F UL Rain Kilt https://www.amazon.com/dp/B07CG5TYBJ/?tag=casaivar02-20
I'm not THAT brave. I do have two pairs of shorts. Or it may be shorts and zip-offs. But, hey, in a pinch baselayer bottoms and a kilt are an ok combination(I clearly don't have the confidence davebugg has if he's wearing that kilt around in the albergue while his clothes are being washed )
I brought my EE rain skirt on my first camino. It was a dark gray, but semi-transparent. I had a couple of uncomfortable hours in a public laundromat doing wash.I'm not THAT brave.

Gaiters are primarily designed to keep non liquid stuff out of boots. Sand, mud, snow, ice. While they can help shed SOME water away from footwear, it is not in their nature to keep water out of shoes and so they will disappoint if used for that purpose. And they will not be much help for puddles and such.The OP included the question of gaiters - will these keep the rain from running into your boots or shoes? I’ve been contemplating this same question but haven’t found anything about the effectiveness of short gaiters for this purpose.
I walked the same time as you in 2017. I had rain pants, not super thick ones and they rolled up to a tiny bundle. Well worth taking as it kept my shorts dry and the warmth in. There were a few rain days where the wind was bad also so I kept reasonably dry with these pants. I’m pleased I took them.
