The main limiter to what you can host is RAM. RPI4s currently go for a premium. Additional they have hidden issues like being picky about power supplies. bottlenecked by IO via USB3 if you want an additional NIC and non-SD storage.
You would be better off with a like-new Dell Wyse 5070 off ebay for ~100 (and occasionally less if you're patient). Supports up to 32GB ram and an M.2 SATA slot.
You'll have much better IO, stability, and capacity compared to RPI4 for not much more cost. Power envelope of the system is pretty similar, the 5070 idles around 5W and loaded down it goes up to ~15W and is fanless which is in the neighborhood of the pi.
