Nothing wrong with Suvarnabhumi, in fact, I'd say it's up there among the least confusing, easiest and quickest to find your way around airports I've been to. Though, immigration queues can be a pain at times.
Many "digital nomads" do get a second passport if they're able to. They also often have 2 phones. 1 for banking and 2FA, which is kept safely at home/hotel, and one with a local sim for carrying around.
