I own the Fyne F704s and feel you are adding too much complexity to your system for no good reason. Just get one good tube amp. No need for 100 watts unless you have a huge room. One good tube amp will sound best.

Want a great integrated amp for your F702s? Get the Circle Labs A200 hybrid Int amp. Tube preamp section coupled with SS output. Your Fyne speakers are a great match for the purity of this amp. This one amp will greatly simplify your system and give you the best sound. Better sound than the two amp approach you are contemplating.
As others pointed out, gain matching will be an issue. In most cases, tube amps will have higher gains that SS amps of the same power rating. Sometimes MUCH higher. This is because they use less feedback, and also the typical input tubes like 12AX7 / 12AT7 / 6SN7 / etc provide a lot of gain.
A Rogue Atlas II (or III the current one?) Magnum is a good 100W tube amp well within your budget. There aren’t too many other budget options like this without going to a no-name Chinese amp (I’m taking about stuff named like Quin-Poo or whatever, not the PrimaLunas which are good).
Your Benchmark has 3 gain settings which helps, but even its highest gain will have trouble keeping up with a 100W tube amp. It looks like the Atlas will be a couple dB hotter than Benchmark’s high gain mode (see Stereophile measurements of Atlas - and they even comment that its gain is lower than usual for a 100W tuber amp!). So you’d need to either insert an additional volume control (and calibrate by ear and/or SPL meter), or re-think your strategy.
Personally, I wouldn’t try bi-amping unless I had two of the EXACT same amp. I’ve even had two of the "same" stereo amp, but there were minor internal differences on the units (made about a year apart), and bi-amping didn’t convince me of any benefits versus running either amp alone. The very slight sonic differences between these units seemingly worked against a cohesive musical whole when bi-amp’d.
Your speakers are designed to be bi wired not passively or actively bi-amped. That said, bi-amping or bi-wiring speakers should not be undertaken without first asking the manufacturer’s advice. See Fyne F702 speaker, crossover below:
