good/important etf's to wheel 3:2 csp:cc?

looking for some worthwhile, worth owning, etfs that aren't too expensive (missed the smh train) and also have high enough iv to make it worth looking into for wheeling. csp into 300 shares, covered call off 200, build up ownership 100 shares at a time. so far, my main targets that are both affordable and barely volatile enough are soxq, lit, nasa, sprt. (honorable mention silj, but idk wtf silver's gonna do longterm). you could do a 2:1 ratio and not deploy as much capital, whatever. i know a lot of you wheel soxl, and some say its not advisable to own (still think so?) but for this discussion im interested in wheeling etfs that i'd want to hold longterm.
