We made the transition off of Dish Net several years ago. The price kept going higher and higher as time went on. Lots of crappy channels with not much to watch.
1. Depending on your area you may have access to many Over The Air (OTA) channels using a simple antenna. These are freely available with a simple antenna and a little effort on your end setting it up. I live in a rural area with only a few OTA channels available but they work fine and look decent since they are all digital these days. Our antenna came from Amazon and cost $45.

2. Streaming is easily available with a decent Internet connection. Most areas have access to decent Internet. You can check your Internet connection speed at: https://www.speedtest.net/
Good Internet streaming TV does require a good connection. Not all ISPs are equal.
We use a Roku. A Roku is a small device that connects to your Internet connection to give you access to various streaming channels. https://www.roku.com
3. Channels I would recommend are:
Locast (by donation) https://www.locast.org/ (depends on location)
Hulu
Amazon Prime
HBOMax
Kanopy (free to some library users)
PBS (included if you donate to PBS)
FreeSpeechTV (free, can donate)
Hoopla (free to some library users)
The above are commercial free basically (except Locast which consists of OTA channels). On the other hand there are tons of other streaming services that base their revenue stream on commercials. If you don't mind watching commercials there is plenty of content available on these free streaming services.
Once you've made the switch you won't look back. TV is actually worth watching again with streaming.
