I could go with a more expensive package like this with a better controller, but is it worth it with 200W?
When you say "you measured", that gives you a footprint of the physical dimensions or real estate you have to mount panels. I am sure you should be able to find panels that fit in that footprint that have different watts outputs greater than 100W. Personally, I would get that highest output panels I could get to fill that footprint. Also get the highest voltage panels you can get and let the MPPT controller convert that to a higher amps input to your batteries. Higher volts and watts per square inch of panel and an MPPT controller will cost more but you will get more bang out of the real estate you have available.
