Sharkbites, and their 2-3 other solderless competitors have worked well for me.

I now keep a “ice storm kit”
with solderless pipe connectors, elbows, and valves.

Trying to get a plumber after an ice storm where electric power goes off and pipes freeze for miles around, and stores empty of plumbing supplies, is a “hard knocks” education.

Dry Ice can also be used to freeze an “ice dam” inside a water line long enough to finish a solder joint.
