I find that I can hammer triceps well after benching OR shoulder work, but benching AND shoulder work don't go together well for me at all. I'm usually a narrow-grip bencher, meaning triceps have a lot more recruitment, and I use a grip that's just barely past shoulders for overhead, so I still get a fair amount of triceps recruitment there as well. That's why I don't do both on the same day and never without at least a day or two between, but I'm always happy to get some extra triceps work at the end of either one, as it has minimal interference overall.
Typically, I find that my front delts get hit the hardest with the benching and pressing (my side delts don't seem to activate extremely well sometimes, so they don't get as fatigued unless I do specific work like lateral raises), so that's one more reason why if I bench first, my shoulders don't work so well for overhead afterward. But, my front delts, like triceps, usually are back to being pretty fresh for training again after 2-3 days, so I don't usually find much interference so long as there's that small gap between sessions.
Like I said, if your condition makes full ROM on shoulders painful, then in such a case, less-than-full ROM may be best for you. If there's pain that isn't just "I'm sore from lifting", then you have to find a way to work around it - and, if you're getting good results from less than full ROM, then you may as well keep at it until it doesn't yield the results you want. My remarks about full ROM to the clavicles on overhead pressing was geared more toward those who don't have any pre-existing conditions to factor in, those who might just be going off of what they heard around the gym, in a magazine, etc. about not lowering all the way. Again, if there's unnatural pain, then steer clear of full ROM and work with what you can. As an old training partner said to me recently, "Sometimes, you just have to admit you can't do all that you used to, and at that point, you have to decide to either train in ways that keep you injury-free, accept that you'll keep getting hurt from not knowing your limitations, or just quit altogether." It was kind of a tough thing to take at the time, as I always keep thinking that I will one day be stronger than I was at my best. Sometimes you just have to be humble, and accept that the road back may be longer, or, that it may not take you as far as you want to go.
For the Romanian Deadlifts, usually, the bar won't touch the floor, and depending on torso/arm/leg length, sometimes you will end the rep with the plates being about 3-6" from reaching the floor. Here's a good description by the late J.V. Askem -

When I do them on rare occasions, I find that it's uncomfortable to do them wiht anything less than about a 2' wide grip, sometimes wider. I find less stress on the shoulders and more delt activation if I go with a wide grip on them, and there's also not the same wrist stress, either. But, you'll handle less weight that way, so that's most likely why you'll see most people doing them with a narrow grip, because you can cheat the weight up a lot easier than when you go wide. I don't consder them an essential movement by any means, just a rare "finisher" I might throw in, but they haven't been a part of a regular training program for me in over a decade, since there are better things to do than put those as the focus.
There's no question, many people have built some great shoulders by not doing as much pressing, but it's much like when people have built great chests by doing flyes, machine work, etc. vs. actual benching. You may end up doing something that inadvertantly puts more stress on the joints in other ways vs. the main movement (such as benching), and while there may be some decent development in time, the overall strength in the muscle and connective tissues won't be the same as doing the more effective compound movement. Again, if they work well particularly in needing to work around a painful spot, totally fine to work around a compound movement, I just rarely suggest going with multiple small isolation exercises vs. a good compound lift because you A) get more bang for your buck by working the most in one lift, and B) it can save time just getting in a few sets of pressing vs. having something like 3 other isolation lifts that are replacing it. Just like how I've got some big freakin' abs and have done almost zero direct ab work in my life, everything that has been built was from squatting, deadlifting, standing overhead presses, and strongman event stuff. But, on that same token, I haven't been particularly focused on bodybuilding (rather, I just want to feel strong again and not get hurt in the process), so there can be more use to doing other things beyond the basic compound stuff depending on your overall mission.
