I found a bunch of threads on felts. Opinions seem almost as varied as, "which kind of oil ?"
Some of the threads are 10+ years old, so I'm not sure if opinions or experiences have changed. But I guess it's my turn to ask.
I pretty much need to re-felt everything on a Monarch Series 61. The wipers I have removed so far were the laminated sandwich type. No longer available, as I understand it. Not a problem as far as I'm concerned, I've used white felts on South Bend's without issue, though I don't know which grade, seller pre-cut and description says "hard" felt. I've sent them a question to ask about it.
Besides wiper felts, I believe I need felts as filters for oil pumps. According to Harry's "another new toy" thread he used F5 for oil pumps. From what I read, he used 3/16" and thought it may have been too thick, as it was difficult to stuff a locking ring on them. But in working pumps by hand on the bench, they worked. I did not see a follow up. At a guess, I'm thinking 1/8" might be better. The F5 grade, not sure.
Having read up on it in the past, I had planned on F10's for wipers. Re-reading, I'm not sure. It seems each guy has used different things, though I don't know if for a particular reason. Most seem to use F5 or F10, But going back to 2008, I saw Cal had a nice thread using F1's, though I don't if there is reason for F1's over F5 or F10:

Checking prices Grainger is cheaper, but McMaster Carr has more detailed descriptions. Looking at their basic chart for specs here:
F1 and F5 fall under "firm". Part of the description I like is "wicking" and "wiping".
Looking at F10, it falls under "soft". Part of description says absorbs oil and grease.
A couple of questions:
1. Which grade for wipers ? Is there a reason, or you tried it and it works ?
2. Which grade for oil pumps ? Is there a reason why that grade?
3. If the retainer is 3/16" in depth, are you using a 3/16" felt, or compressing a 1/4" felt ?
4. How are you cutting it ? Scissors, razor blade, hammer and chisel ? or something else ?
5. At a guess, the softer the grade, the easier it may be to get compressed down on ways to start retainer. But I wonder if if softer or harder would make a difference in collecting or pushing fine chips and debris away.
