Get a PDU or metered PDU on a dedicated breaker.
You can get either 120v or 240v PDU, but I would recommend getting 240v as almost all PSU allow both 120/240v usage. You many need to invest in C13 to C14 cables.
Example of 240v 30a pdu (240 x 30 = 7200 watts less 20% = 5760 usable watts).
You'll need an outlet for the dedicated breaker that looks like one one below.

I have both 120v and 240v metered pdus.
Will 2 240v 30a running to 2 L6-30P receptacles be OK?
It will be more then enough to run a single S19j Pro.
Each 30 amp 240v will allow for
30 x 240 = 7200 watts x 80% rule = 5,760 watts max
what size wire needs to be used for the run?
For 30 amp you will need 10/3 gauge.
do I need it setup with a specific phase type?
No, single phase is fine.
Can I use 2 of these tripp lite pdus and to plug the s19j pro into? https://www.amazon.com/Tripp-Lite-Outlets-Rack-Mount-PDU1230/dp/B0007YG85A/ref=sr_1_1?dchild=1&keywords=tripp+lite+30a&qid=1627699378&s=electronics&sr=1-1
Yes you can, but you need twist lock connectors.

Can I use these 15amp cables to plug the antminer into the pdus? https://www.amazon.com/Tripp-Lite-Computer-IEC-320-C13-P007-003/dp/B00JT0DG94
Absolutely Not. That is a 120v cable.
You want to use c13 to c14 cable if you are using those pdus.
I also plan on plugging some eth rigs along with btc miner into pdus for a total of around 6,000w. Will this be OK or do I need 3 l6-30P receptacles installed?
With 2 x 30 amp 240v receptacles, you will have 5760 x 2 = 11,520 watts available.
You will probably need additional c13 to c14 cables for the gpu miner psu. Just double check the label that it can support both 120/240v (All of the equipment I have for the most part can do both, even your monitors can if you look closely-also c13 to c14).
Your electrician should also check the loads on each bus bar to ensure that the loads are balances since you will be drawing a high continuous current.
