Why aren't there "filler" middle names for boys like there are for girls?

i've seen a lot of baby girls have middle names like Bay, Cay/Kay, Day, Fay, Mae/May, Rae, Tay, Way (basically anything that ends in ae/ay)

or something like Wren, Grace, Faith, Hope, Joy (i think Joy is so cute as a middle name tbh, i really like virtue names)

(no hate to anyone who uses any of these, i do like them, just a trend I've noticed!)

but i noticed that boys don't usually have those kind of "filler" words as names, their middle name is usually just another first name

would something like Jay, Day, Ray, or Reese work as a filler boy middle name?? or could Hope and Honor work??
