Best Way to Allocate $5K Toward a Home Strength Setup

Got a $5K windfall and want to build a solid home strength setup. Priorities are: safety, compound lifts, and future expandability.

My plan: NT-CB1 combo rack, AB2 bench, NT-10014 adjustable dumbbells, and a basic barbell. I considered REP Fitness, but I can stretch further with Ntaifitness on my budget.

What else would you add to maximize a starter budget? Platform? Pulley add-ons?
