I'm just struggling with whether I'm shocked by your criteria for "your needs", or being dumbfounded that you live in an area where not 1 gym you had to choose from had a cable crossover set-up of some sort. 
In 25+ years of working out, and working at gyms; the only places I've ever been in that didn't were my middle school and high school weight rooms. It's just so standard. Most gym layouts are either built away from, or around at least one multi-station with a crossover section.
I'm not challenging you that you can put a great home gym together without one, and get good results though.
i didn't say not 1 gym in my area has one. i know one that definitely does, as i've used it but it's a very expensive health club type of place that i go to occasionally with a friend who is a member. but even if i needed a gym membership (which i don't) i wouldn't join it as it's probably around £130+ per month.
also most of the gyms i have been a member of are not been built around a multi station either. i would love one in my home gym (cable cross) but i don't really have space and tbh i have enough equipment already that i can hit every body part quite sufficiently.
i have a leg extension/hamstring machine, a lat pull down cable machine(free weight load) which you can do tricep push downs/bicep curls/seated rows etc . a hyper extension bench (excellent movement for lower back) a machine that you can use for shoulder/chest press from decline to incline/also bent over rows.
a bicep/tricep preacher curl type machine and a hack squat/leg press/calf raise machine. all body solid machines free weight loaders.
on top of that i have a power rack (cage that has spotter/catcher bars can be used for various free weight exercises, bench press/squat/rack pulls, pull ups, dips and a ton more. and i have a bench, dumbells and a various barbells.....and a treadmill
so i really have all i need tbh.
ps also i'm not talking about a "cable cross set up of some sort"....i'm talking about the type that has 2 posts that are a good distance apart that you can use for the cable fly exercise. the things with like one post and cables for various exercises i think i have seen more commonly
