Some things to consider in hopes you get the best value, performance, and future proofing. Stick with name brands as you will see the stated power output on the specification sheet. At this time it makes little sense to purchase anything less than a POE+ switch.
16 channels is the lowest in terms of port count I would go. If you feel spendy go for a 24~48 port POE+ switch because there's room to grow and you spent your money once! When you move up past 16 ports almost all of these POE+ switches have a fan and some are louder than others. While others use PWM fans which ramp up and down based on the real world temperatures.
Meaning you're not inundated by fan noise . . .
This leads to any 1st tier hardware maker and should know and accept the vast majority sound like a jet plane! These same very reliable (yet cheaply had via eBay) also consume a huge amount of power. This is a core piece of hardware running 24.7.365 so energy consumption should be top of mind.
Especially if you live in a area where the KWH breaks $0.12 and over . . .
Many of the 1st tier Enterprise hardware incorporate SFP / SFP+ which is optical fiber ports. In the big picture its not needed but if you have long runs and want the extra performance that comes with fiber having these ports is needed. One of the huge advantages of using fiber is absolutely no impact from RFI / EMI. Allows long distances which assure consistent high speed 1GB / 10 GB transmission.
From a safety view point its one of the major corner stones in protecting the homes internal network infrastructure. So consider all of the above before you part with some hard earned green backs and purchase a 3rd tier piece of hardware that simply doesn't offer a known and predictable outcome.
Lastly, in the 16 ~ 48 port switches a 150 watts is the bare minimum and 250 / 500 is the sweet spot for years of growth and expansion.
Buy once - Cry Once . . .
