Help me choose an FPGA to design network protocols

Since many people have suggested Arty, I was giving it a serious thought. B ut although it does have ethernet (which I need), it does not have any kind of video output like VGA (I would strongly prefer to get a board with some kind of video output as well besides ethernet). I do not want to try and a dd VGA to it as I have no experience with that stuff. Another Digilent boar d that I really liked is the Nexys 4 DDR, which has both ethernet and VGA. But the price is a little over my budget at $320. I am trying to do this wi thin $200, although I it can go up a bit (to maybe $300) if I don't find an y good option in the "< $200" range.

To re-iterate, I am looking for a board with a Xilinx FPGA (preferably Arti x-7) that uses the Vivado software. And as stated above, I want ethernet an d video output connectivity support. So now that I have a clearer idea than before, if somebody can suggest a board meeting the above requirements (in the $200 range), that will be great.

So far I had only been looking at boards from Digilent, but I just came acr oss another company called Avnet which also sells Xilinx boards. They seem to have a lot more choices when I search for a board with Artix-7 (while Di gilent has only 3 or 4). I didn't understand very clearly what type of boar ds they sell. Do they make them or do they just distribute the boards made by Xilinx? Which one would be a better option - Digilent or Avnet? Or somet hing else?

Thanks.

if you had any current experience you would know that the name is Vivado and that Xilinx have all versions of design tools going back something like
