(I realise going to a shop to try masks for fit would be best but time and work doesnt permit)
This.
It’s the same as walking books, you can buy the blingest, most high tech sexiest design but if they don’t fit they are useless. Always go for the best fit.
You could always buy 3 different masks mail order and return the ones that don’t fit?
It’s a bit like the CRC v LBS problem, sometimes you need to spend the time and money to get the right fit.
You will probably be looking at slipper fins, however, even in warm water I prefer a open fin with a wet suit boot.
Also, I would recommend buying the simplest snorkel possible, avoid drain valves and stuff.
