The cord with breaker is fine, but limits you to the 20 amp circuit. You need the sub panel to run both tools. I don’t care what possibly unsafe adapters are sold, many without UL testing and listing. I will not use them in my house or shop, and would never tell anyone to use one in theirs. Is the wire in that un protected and adapter 10 or 12 or 14 wire? We do not know without cutting it apart. There is a reason for the testing and listing. As for getting deep into the NEC sections about motors and fusing and using smaller conductors on breakers sized larger to not trip on start up, that is beyond understanding to people that are not familiar with code language. I don’t understand computer language. Everyone has their expertise. As for magnetic motor starters, any name brand is fine. Square D, Allen Bradley, Siemens, ABB, Cutler Hammer. Whatever is available and fits your budget. There are switches with overload protection, but not being magnetically held, the motor can restart after a power interruption.
