Warm welcome to the PNW Robin. Here is a web site I have found helpful. It is from King County but I find it works for most of the western slope of the PNW. https://green2.kingcounty.gov/...
You might also do a search for native nurseries in your area and/or nurseries that have a native section. Favorites for me:
Indian plum for early bloom, will naturalize and provides a good summer screen
Ribes for bright pop of spring color
Vine maple for gorgeous fall color
Ferns of all types - sword, deer, parsley, whatever I find out in my back woods I will move up to the yard. Sword ferns are a bit aggressive and need some room, but make a nice statement if you have room for them.
I also let my native groundcovers colonize as they like - little purple bleeding heart, false lily of the valley, both are spring bloomers, usually melt away by mid summer.
My nemesis is creeping buttercup - it wants to take over my world. On the other hand, it does have jolly yellow flowers and often non-gardeners think I have planted them intentionally.
A fun near-native (I think more common a bit further south into Oregon) is Darmera - very dramatic both in bloom and the huge green leaves.
I encourage everyone to embrace natives - good for the wildlife, pollinators, easy care, and just a nice look.
