With a Ring Doorbell Pro (wired for direct connection with one doorbell with less than 25' circuit), I'm looking at an Elk transformer that will plug into an outlet inside the house. Which model would you suggest and why? 24VAC 40VA VS 16.5VAC 45VA?

The Ring Video Doorbell Pro 2 is, requires a doorbell transformer rated at 16-24 VAC 50/60HZ, 30-40VA max.

What happens when Ring gets 45VA when they state that 40VA is the max?

The VA rating is strictly what the transformer is capable of supplying. The doorbell, Ring or any other, will only use as much power as it needs at either specific voltage level exactly the way a 100 watt light bulb is connected to a 15 amp, 1750 watt, power connection.

So it’s okay to have more VA but if the supply had 28 volts instead of 24 without a load that may be more of a problem, yes?
 
Again, think about a light bulb. If the supply voltage is 110, it's fine. If the supply voltage is 120, it's fine. You're also looking at a no load voltage reading. Under load that reading will drop and may easily drop below "rated" voltage.

General rule is if your Chime is working on 16 volts, your replacement trans. should be 16 volts, if 24 then the same. When you increase the voltage on a Mechanical Chime it will increase the hammer strike which will increase the volume of the chime and possibly decrease the life of the Chime.

I had a 16v 10VA trans. that I replaced with a 16v 30VA trans. Smart Doorbells need constant power and use more Amps (VA) when Chime is used.

Lastly, be sure and use the power kit that came with your doorbell, it actually regulates this increase in power...

I’m wiring the doorbell directly to the transformer with only about 15 feet of cable. Probably going to buy the 16.5v 45va Elk transformer. How would the power kit be wired in and what will it do?

So no Chime? If not, no power kit needed.

The power kit keeps the mechanical doorbell from humming. All it actually is, is a resistor to bypass some current around the coil to prevent humming or buzzing at 60Hz.

Yep the Chime...
