SO-DIMM vs DIMM is a specification, they're still different. https://en.wikipedia.org/wiki/DIMM
288 pin vs 262 pin in DDR5 https://www.techtarget.com/searchstorage/tip/Compare-DIMM-vs-SO-DIMM-features-uses has a nice picture of the memory size differences. A lot of smaller form factor devices use SODIMM for size constraints. The bigger memory hasn't gone away, and the same pros and cons mostly exist between them, with the larger surface area of a DIMM able to hold harger and more numerous chips.
