Trying to understand what makes an actual “strain”???

So I’ve been doing a lot of reading, and it’s my understanding that a lot of these “strains” that are f1 crosses? (Plant a x plant b) will produce many different phenotypes (completely understand phenotype) but there’s strains that are considered more so true strains that are f5+ that will produce the same pheno maybe 2/3 and they’re considered more solid strains for that?

Couple questions
What’s the difference between f1/s1? S1 is a female that’s “selfed” to make seeds and a f1 is male female pollinated?

If i pheno hunted one of these hype strains say 100 plants and either selfed the best female i could find or find a good male i like and pollinate would that make those seeds F2? And do the same over and over again picking traits?

Last question where did inbred line IBL fall in?
