BOB (or other single wheel) for handling and riding at any decent speed, but add a stand for ease of loading/propping.
2-wheel style for lugging very bulky or lopsided loads, but not for going fast and beware of extra width!
The cheaper trailers are great for occasional use or ‘seeing if it works for you’ tests, but the posh ones are expensive for a reason, they are way better built, more robust, more stable and last longer. If you’re going to be using it very regularly or with very heavy loads it’s worth spending the extra, but not for the occasional trip.
Whatever you go for pay attention to the hitch, some of them can be challenging to make work on some frames, some are easy to port between bikes, others not. Sadly the most secure hitches are often the most faff too!
