I fish topwaters, hard jerkbaits, and cranks on a medium/mod Falcon Bucoo. I'm not shilling for this rod specifically so much as backing up @Drawdown's thinking with an anecdote because I'm procrastinating.
It really all depends on how deep a plug you intend to fish.
I think braid to leader makes a lot of sense with a multirole rig like you're asking about because the braid seems to claw back a little bit of the backbone that I lost going with the blank I did for the specific rod I discussed above. YMMV, of course.
If I had it to do over again, I'd go medium/fast, and I'd probably still keep the braid, and I'd have more options.
Multirole rigs may not excel at any one thing, but they can be awfully good at a lot of things.
