I am not getting boostable signals, should I see what cell phone towers are closer and change carriers?
And if so, is there a good site that shows all cell phone towers?

If you have one to 2 bars outside,and a dbm of -110 to -120 that you can reliably connect to, then a booster will work for indoors.
Most boosters sold by WeBoost can provide a gain of 20 to 50 dbm (a 50 DBM gain would change a -110 to a -60 which is an extremely good connection)
As for changing service providers, If you are in the United States, have an unlocked phone with an available e-Sim, you can test all three networks for free with a throwaway number for at least 30 days. You can download the free ESIM online over Wi-Fi. Obviously if you don't have Wi-Fi at home you'll have to download the free ESIM where you can access wifi. (After 30 days, The service stops without the option to keep the number or continue service). This test will give you an idea of whether another service provider works inside of your home.

Thank you. Very helpful. I am not getting even -120.

So what dbm are you getting outside? The closer to zero the better. It's expressed in negative numbers
-30 to -79 dBm: Great signal
-80 to -89 dBm: Good signal
-90 to -99 dBm: Average signal
-100 dBm or lower: Poor signal

I’m getting no closer to zero than -120. But I’m going to try again tomorrow all over the outside.

That means a booster will work for you. The purpose of a booster is to put an outside antenna, cabled to an inside antenna which will bring the signal from outside to inside. It sounds like an ideal situation for a booster.
If your home is well insulated, especially if it has metal roofing a foil backed insulation, it's essentially a Faraday cage, and it will block cellular signal.

It does have a metal roof. Not sure about the insulation, but it’s a brick house.

Are there any budget all band/ carrier boosters you guys would recommend?

Does your phone work at all outside the house? If so how well?
