As a British Columbia (BC) resident I may be slightly biased. Having shot many back bears and many colors phase black bears, plus 3 BC grizz, before our fool Gov decided to "manage by emotion" and close it down. I must say I love bear hunting, best is spring from my boat with kayaks on roof, spot the "right" one, anchor, launch and stalk the correct wind. This is an annual spring hunt. I am lucky but I cant hunt roos, pigs, or all other wants you have.
I say you need to set your parameters, must haves, needs, wants and nice to haves before any advice, places or outfitters can be recommended.
What do you want from your hunt?
Relaxing, backpack, physical, fancy accommodations, wall tent? Seeing bears every day or just the "one" you want to shoot? Bait, spot and stalk, dogs, spring, fall, size and lots more answers before any place can be narrowed down. Then even more specifics, spouse along, kids accompanying, mountain hunt, beach boat hunt, riding on ATV, truck, drift a river, watch a grain field, walk the bog/tussock, sit in a tree, you mention color phase so some areas are excluded (Vancouver Island) and of course cost/budget?
As for weapon, I would answer the questions above and narrow down what the hunt will be, then I pick caliber and weapon based on these answers, South Carolina monster blacks can go 800+ lbs (my bucket bear), BC coastal and interior bears may be 400 lbs but sometimes one must stalk past 1000lb grizz to get your black (fun), size differs dramatically from coast to coast of NA. In all places its best to anchor him down right there, dragging a bear is not fun. Packing out is also tough.
With a couple hours internet searching and a few specific answers to what your hunt must be there are tons of experienced pers on here that can and will willingly provide first hand details to assist you.
Let your fun begin.
