I keep wine yeast unopened for about 2 - 2 1/2 years okay.
after it has been opened i think it will keep in freezer for about 6 months if you keep it in an airtight container.
Test it by combining about 1/2 cup warm water, maybe 110-120 deg. and a spoonfull of sugar. then add about 2 tbs of dry room temp yeast. it should nearly double in size to a cup or so within 15 min.
Yeast is cheap so replace it if unsure.
Its still good then. I know from wine-making that different yeast strain greatly effect taste of the finished product. Spent 3 years working on some wild strains of yeast for wines......never do that again, terrible.
I have only made no-yeast hardy types of bread, Irish bread, soudough etc... don't know about the yeast strains used. Bread is an art-form, I'm sure you will find that recipe your family will enjoy.
I have bread yeast from bulk packs at Sam's Club that has been opened for over a year now that still worked just fine last night on some pizza dough. I just keep it in a ziplock bag and scoop it out as needed. It was probably kept over a year in it's vacuum-sealed foil bag before that. The freezer is your friend when it comes to yeast.
