The above is a great video which shows the efficiencies of trading SPY or XSP $5 or $10 wide wings on a 20 delta IC. $5 wings costs you $500 in margin, compared to $5,000 per contract @ SPX. SPX and XSP are the same thing, just SPX 10x the size of XSP.
example @48 dte, pretty close to 20delta and $5 wide. $5 as low as you can go with XSP. an advantage of trading smaller contracts, besides lower margin, is you can scale in/out larger numbers
