You need the output of "path one" to go to the input of "path two" and have the output of "path two” go to whatever your output is (the XLR, Headphones, or 1/4 output or whatever).
From there you can split path one and two into different directions.
Based on what you’re saying, the most logical thing would be to put the Amp and Cab blocks towards the end of path one, with the delays and reverbs in path two, using the split and merge blocks in path two to get the signal chain however you want it.
(Me personally I always put the cab last, to get a more accurate "actual amp in the room sound,” and only put reverb after the cab in specific circumstances. I also move the microphone pretty far away in the cab block’s settings. You can do whatever you want and a lot of people swear by putting delay and Reverb, and even some modulation, at the very end. This is also very dependent on if you’re just playing guitar for fun in your bedroom or actually recording with an interface.)
If you don’t have enough DSP in path two to get everything, there’s probably still plenty of DSP left in path one. You can move the Cab block earlier and throw whatever your earlier delays in the signal chain are there before it outputs to path two. It shouldn’t make any difference compared to if it was the first block in path two.
Also, don’t be afraid to go into the Legacy effects where you find all of the old Pod/DL4/MM4/etc models. They’re not as DSP heavy and still sound really good. I often gravitate towards the Legacy delays over the newer ones. It’s literally the same algorithms as the DL4, which over the years has become an iconic delay pedal on the level of the DM-2, Memory Man, Roland Space Echo, MXR Carbon Copy etc.
