Where's the C1 love? C1 on CH is also nice. C1A on CH can lead into a free CB if not shaken fast enough. C2A is great for slowing the tempo down and chipping at the gauge. If you land it, it gives range.
My advice is to not always look and wait for big damage. Hilde has a pretty decent move list (I wish more mids had good pushback), so incorporating moves into charge setups is really fun. For example, I love 7K because it retreats well (screw backdash), its fast, and can wall splat. Sprinkle in a wider than it looks C3B in and you got a filler for the gap created. 7K, C3B - my favorite. Personally I like to give that false illusion of safety to attack then throw out a charge move.
If you got a charge move that will hit, you might as well use it. I use CR C3B,B,A all the time for people that like to wait on the floor. Even if they stay down and I only get the hit of the 2nd B, it's better than nothing. I find that people rarely block the last hit of CR C3A,K,A . . . that's pretty much free damage if they see the B ender can launch.
