Airport processing times/time to/from Hamilton?

I am an American who will be traveling to Bermuda next week. I haven't been since before Covid so I only know the old airport!

How long does it typically take to get through passport control and customs these days? If my flight arrives mid-afternoon, how long should I expect the cab ride to Hamilton to take?

On the way back, what time would you recommend I leave Hamilton for a 2:45 flight? (Hand luggage only; Global Entry member.)

Oh, and I know the weather's been bad and next week should be rainy. How warmly should I dress?

Thanks so much!
