I recommend looking at the Bosch 800 series and the Ge Profile line, here is a buying guide I just did on it.

There are a few on the market. GE and Whirlpool with precise fill come to mind. You can press, say 1/4, 1/2, etc. It will dispense just like a measuring cup. A handy feature to have! here is a great video on it https://products.geappliances.com/appliance/gea-support-search-content?contentId=18333

If a front loader, it depends on the model. If manufactured by LG or Samsung, it will be in the lower front, behind the trap door. If manufactured for them by Whirlpool or Electrolux, it is by the pump behind the front panel, so not as accessible.

This is true as they sold out, and now the name is just used for select products. But they no longer manufacture themselves. Is it a gas or an electric oven? In gas, Frigidaire still makes a 24 by 40 unit. If electric, look at Whirlpool brand as they make many sizes as well.
