The Pull Payment method from the card issuer's site, is an ACH payment - the money is pulled from your linked bank via the Automatic Clearing House system that virtually ANY and EVERY financial institution in this country is a member.

Using both linked checking accounts AND WMBP, does NOT cause issues. Using more than 3 linked checking accounts seem inevitable get payments being put on hold until the same account has been used a few times. Just think about it, most people would not use more than 2 bank accounts to pay bills. Why there is a need to use so many bank accounts? That naturally raises flags.

Using 5 linked accounts definitely could trip wire based on the tidbits heard over the years.

Many payments within a billing cycle also is a flag raiser.

Citi only allows 4 payments in a billing cycle when it is pull from the linked bank account. Although you certainly can push additional payments in to bypass the limit.
The counter act from the bank is NOT to release the payment amount to your Available Credit. So no matter how many times you pay, you are not going to "increase" your CL in a rapid fashion.
