I only brew 5 gallon batches because of a few different reasons. Any reasons why not to consider using a March pump to transfer liquids between sparge tank, mash tun to boil kettle? I do a gravity brew so I think that alleviates the priming issue.
I don't use a March pump at all, never ever.
I use a Chugger pump. One of the better investments I have made in my brewing extravaganza.
The usual reason given for avoiding pumps is that they shear proteins.
I would be completely flabbergasted if that was true. Can you please cite a source of some sort?
As a general question: How is a pump hard to clean? Capture hot water in a HLT, add PBW and pump to your empty kettle. Clean kettle and dump PBW. If you want to rinse, fill your kettle with water and recirculate through the pump.
Clean.
Every couple of brews you can take apart the pump head with four screws. There's way more gunk lurking in your ball valves then there is in a pump head.
My original thought was it would help suck additional liquid out of the mash grains and faster.
I also have a little giant and have never had a priming issue. You can also run them dry for quite a long time before there is any damage, unlike the march or chugger which can't be run dry
...with Midwest 20% for veterans...But I am just thinking that with 5 gallons it is just not worth it.
Pretty sure you should not run any centrifugal pump dry, where are you getting that info from?

run dry time 8 hours
The usual reason given for avoiding pumps is that they shear proteins. As do so many of us I use pumps all the time (including for recirculation in the mash tun). The beer still comes out pretty good and as there really isn't any alternative I guess I'll never know what 'unsheared' beer tastes like.
