Why 30a (120v) at Home?
Curious what the extra 15a is for. We only ever need 15a at home where we park the rig and leave it on shore power all the time. 15a does battery charging and any fridge time on 120v. What else...

If for no other reason, the 30 amp plug is a much more reliable connection than a standard wall plug. 15a, 30a, 50a is all 120V, just a matter of wiring and the cost difference between running a new 15a line or a new 30a line is minimal.
Careful here. The 50a outlet is a 240v outlet. Most RVs just use the legs separately giving them 120v on each leg. But to label it as a 120v outlet is misleading. The 50a outlet is wired EXACTLY like your 4 pin 240v dryer outlet and uses a ganged 240v breaker.
No, I don't need to be careful. The installer might want to be careful that they wire the plug properly. There is NEVER a 240V circuit available on a properly wired 50 amp RV plug.
"NEVER" is a big word. The people with a 240v dryer in their RV might beg to differ. And, yes, some folks do have a 240v dryer in their RV. But, if you take your multimeter between the two hot legs of a 50 amp outlet, I think you will find 240v, even if most RVs don't use it that way.
