GoPro N00b needs Export Settings

I'm recording mountain bike videos using a GoPro Hero 5 Session recording at 2.7K 30 FPS.

I looked up a lot of videos in my "research" for best exporting settings in Premiere Pro. I went with what was most common between a bunch of different videos. Most of them were saying the same stuff. The Main thing (I think) I'm hung up on is CBR vs. VBR 2 Pass. (Everyone says VBR 1 Pass is pointless.)

I was using CBR first, and that exported a lot faster. (Uploading to Youtube is a whole other thing. That took 12 hours for this 25 minute video.) Once I stumbled upon the VBR 2 Pass option, I tried that. I exported in both CBR and VBR 2P to see if I could spot the difference. I couldn't tell it apart but 90% of people say VBR 2 Pass is the best quality. (However they're also filming with LEGIT cameras and not Go Pros?) I thought, Ok.... maybe the difference will be when I upload it to YouTube. Maybe that's where I'll see the difference. But in that case, I'd have to upload two videos and play them side to side... I originally said no to that. Too much work and time Uploading. I then deleted one of the files. I wish I didn't. So today's video I'm exporting in VBR 2P, it is only 10 minutes long and incredibly simple with very few files although it has a highlight effect on the wole video. It took 8 hours and that's with it being rendered previously to Exporting. So I started researching again. Trying to find faster ways to Export.

One thing is "smart rendering" but that's not an option because it isn't yet formatted for encoding MP4.

The other hot tip was to Queue stuff instead of Export it. Queuing stuff sends it to Media Encoder to do. However, mine isn't functional.

I also realised that my copy of PP is installed on the Solid State Drive but I've been saving things to the Hard Drive. So I thought maybe that was slowing things down? So then I cancelled this Export and Saved it to the Solid State thinking I can just move it later and it made no difference.

I guess the last thing is... My Target Bit Rate. That was a big discrepancy with most people. The Max Bit Rate hovered between 32 and 40 for most so I put mine at 35. But some people had their Target at 8, or 16, or 32. I decided to go with 16, that's the YouTube suggested one. I don't know if that's what's making a difference. One guy just had them both set to 32...

I want the best quality, first and foremost, but I also need to find the fastest way to export without sacrificing quality. I'm afraid i'm going overkill right now and wasting a lot of unnecessary HOURS exporting for a 10 minute video. I have 2 hour videos planned... This isn't going to cut it.
