Ill throw in some input, take it with a grain of salt; TLDR = (EVERYTHING HERE IS IN REGARDS TO STREET CARS NATURALLY ASPIRATED) small cams are generally easier to make civil, big cams needs more gear and stall, making them much harder to drive on the street. Bigger cams (don't mistake with over-camming) can run hard if you build the car to run in the upper RPMs. If I were you, open a new tab, get the numbers to Cam Motion, Comp, Lunati, Tick and all the others and ask THEM. Who would have better info about THEIR cams?
Bigger cams require more gear and stall. Means more heat, bucking a surging while cruising in overdrive and in traffic. The make more power up top, and you may want to raise the rev limit quite a bit to take advantage of this power, which means more $$$ to make sure nothing breaks when you spin to 7500. Big cams have more overlap generally speaking, increasing reversion at low RPMs, soiling low end torque, increasing scavenging at high rpm making that much more power up top. Decreases vacuum, makes power brakes mushy. Small cams make more low end torque and less overlap, more drive-able and easier to tune. If you do it right it will drive like stock with a mild lope and more power overall. Don't necessarily need to rev high to make power, needs less stall, less heat = longer tranny life. Doesn't sound as cool with less overlap. Vacuum is usually good enough to run power brakes no problem. Should cruise in traffic and freeways no problem. As far as lift goes, my theory is if I run 243/799 heads that flow generally speaking 256 cfm at 550 and 257 at 600, why run cams with 600+ lift for gains not worth bragging about? Just more wear and tear. Means replacing springs more often. But if you want max effort and don't care, or have aftermarket/ported factory heads then things change.
As for ETs on the track? Hard to tell without going out yourself and talking to others personally. From what I have seen in regards to STREET CARS big cams are dogs unless you build the car to run at a much higher RPM, which hurts street-ability, street-ability is completely subjective btw. Big 230+ cams running mid 11s. Then there are much more tame 224/224 cams running...mid 11s. Then I see 220/224s running mid 11s. Sure you can make 230+ cams run low 11s high 10s on stock cubes but then your car is much (not harder) but annoying to drive on the street. Many people don't mind lots of overlap and high stall speeds, or maybe you don't want to sound like an 11 second pro-stocker. I personally don't want to have bigger bark than bite when I get owned by a stealth turbo sleeper junkyard build colorado...But maybe you like the way it feels and sounds, its a second kind of cool thing, do what you want its your car.
