If your clay soil is well-drained (no standing water in winter) you shouldn't have to worry too much about it. Put a thick mulch of arborist's wood chips over it, and it will not only improve the soil over time, but keep it from drying and cracking in the summer.
There are several non-Doug fir conifers that are fine with clay soil, including Picea abies (Norway spruce), Picea glauca var. densata (Black Hills spruce), Pinus nigra (Austrian pine), Pinus strobus (White pine)
Pinus sylvestris (Scots pine), Pinus ponderosa (Ponderosa pine)
Evergreen broadleaf trees that you could try include Magnolia grandiflora and it's many cultivars, Chrysolepis chrysophylla (Golden chinkapin) a lovely but seldom-grown native tree, https://landscapeplants.oregonstate.edu/plants/chrysolepis-chrysophylla.
Nothofagus dombeyi (evergreen beech), which gets quite large eventually, https://landscapeplants.oregonstate.edu/plants/nothofagus-dombeyi
Prunus lusitanica (Portuguese cherry laurel) (I wouldn't recommend English laurel, Prunus laurocerasus).
Or if you are willing to have a slower-growing tree, one of the evergreen oaks. Here's a whole list.
Quercus agrifolia (Coast Live Oak)
Quercus berberidifolia (California Scrub Oak )
Quercus chrysolepis (Canyon Live Oak)
Quercus emoryi (Emory Oak)
Quercus engelmannii (Engelmann Oak)
Quercus glauca (Japanese Blue Oak)
Quercus hypoleucoides (Silverleaf Oak)
Quercus ilex (Holly Oak )
Quercus myrsinifolia (Chinese Evergreen Oak )
Quercus suber (Cork Oak)
Quercus wislizeni (Interior Live Oak )
