Yes strawberry would work. ANYTHING you can think of can be added. I once made a jalapeno mead that was really incredible. I would cut the strawberrys up into chunks and make sure they're washed. They have a fairly mild flavour compared to honey so don't be afraid to add lots. 1 : 1 ratio with the honey or a little more should be good.
I would suggest getting an actual fermentation pale with an
airlock. Sometimes with fruit (and always with aggressively fermenting things like beer) I would use a large tube the fits into the hole in the lid fed into a bucket filled with water. This is basically a large scale airlock often called a
'blowoff' tube.
Edit: added link to blowoff tube example
