Why do 235 engines have at least 3 types of oil strainer configuration. Attached are pictures 3 configuration. The first one is my actual configuration. The other 2, one is from Deve’s Technet, the other is from The Jayhawker YouTube file.
Your first pic matched what I saw on a 1958 235 I had with the pivoting pickup. The last one matches what's on my 1951 216.
Probably just GM building "better mousetraps". Or the bean counters telling the engineers to make them cheaper. The 216 style has lots of parts compared to the later ones.

I just took a look at the crankshaft supports and the one I’m pointing to in the attached picture is threaded for bolting the strainer in other types of strainer installation.

Yep, that's a 216 style bearing cap. Might be a carry over from an earlier engine. What year is the block you have? The bearings are interchangeable between 216 and 235 on that bearing journal. The only one that's different is the thrust bearing with the flanges on either side.
Here's a pic of that strainer pedestal on my 216 when I adapted a higher capacity oil pump.
Another pic of the difference between 216 and 235 thrust bearings.
