It's worth looking at julia's JuMP, I find it very ergonomic, fast, and easy to try differnet LP solvers

Also https://neos-server.org/neos/solvers/index.html is an amazing resource I don't see used often. These solvers are very expensive and it's not obvious which solver will solve a given problem fastest (if it supports the problem's type) because it depends on which heuristics they use. So you can submit example (medium-sized) problems here, try out a bunch, and get your company/buy the one which you know works best
