T Top is definitely the way to go if you intend to do lots of fishing. A Frames do really get in the way when trolling or spinning.
Your best approach would be to try a few different hulls if possible for the sea handling characteristics /size etc and once decided then speak to the builder who will easily be able to install a custom console / T Top and leaning post as required to your specification.
Many of these are available from places like www.basspro.com
in the US. Alltackle also do every type of outrigger imaginable that can be mounted onto rails, rod holders, deck etc etc.
Landing large fish should not be a problem as you can have a large plastic drum cut down to sit over a tube for you to drag fish onboard over as we do with a bag full of scallops that have razor sharp edges. However, once the fish are onboard that may give you another problem??
Good Luck with the fishing and boat search.
The biggest fish we get round here are Tope to 50lb or the odd Porbeagle to about 250lb.
