I think it's most important to pick a playstyle that you enjoy. I don't look at builds for a variety of reasons, but a major one is that it doesn't matter how "good" someone else's build is if it doesn't reflect a playstyle I would like doing (or be capable of doing). Experiment with different things yourself to see what you like and what you don't (which often depends on context, by the by).

Wardens in particular are very flexible in terms of what they can do. As someone who is role-play focused, I come up with character concept first and try to figure out how to make the game mechanics do what I envision. I won't bother you with the details of that in this forum, but the play style that came out of it happened to be one I found really fun in PvP while also working for what I like in PvE. She's a stamina build who is bow/bow and has high stamina regen. Eternal Hunt is her cornerstone set, so she's dodge rolling constantly and leaves those poison traps all over. I used to pair that with Senche's Bite, but currently I use Gryphon's Ferocity as it fits her character much better. She's multi-modal in terms of how she can approach engagements. I keep a couple heals on bar to assist her allies when sieging. When she's able, she strikes from stealth with snipe then pelts them with more arrows. But most of the time, she's dodging and running in circles around enemies. If they don't chase me, they get hit by Sellistrix stuns. If they do chase me, they get hit by immobilizing poison traps. It doesn't always work well in practice, but boy, it's fun.
