Are you thinking delta or tadpole ??
Deltas tend to have higher seats so it's easier to get on and off them.
But it fairly easy to fit grab handles to a tadpole if that's a problem.
Being lower tadpoles are more stable if you think you'll be doing silly high speed corners.
Deltas tend not to have that much weight on their front wheel.
So it's possible to lose steering on a steep gravelly uphill track, especially if you only have a single wheel drive.
Tadpoles are the opposite in there's less weight on their back wheel, so you lose traction and you'll have to get off and push instead.
Hub brakes are fit and forget, they are also more weather proof.
Disks tend to have more stopping power, very good if you have a weak grip or are running twin brakes off a single lever.
Recumbents tend to favour a high cadence riding style.
So shorter cranks and slightly lower gears may be an idea.
Mesh seats are cooler and more forgiving, but hard shell seats tend to lock you in place so you can generate more power.
A front fairing can give you ~4% more top speed on downhill runs, so not a lot.
But it does make the trike look bigger from the front, so maybe better in traffic.
Luck .............
Ps. If you do a lot of off road/shared path cycling then a good "bing-bong" bell is a must.
