Easy TV just for cable?

My family and I are looking for a new TV for my grandma because the one she currently has is too confusing. All she needs is cable. She doesn't use any streaming services. I've heard people recommend Roku TVs as good choices for seniors, but it looks like they all have a built in home screen with all the streaming apps. Are there any TVs out there where you can literally just have one remote to turn on the TV and it opens straight to cable? Thanks.
