Phoebert -
That's crazy! So much different out here. The varieties you can buy at your local Home Depot or even nursery here are prob the same or close to the same as what you get there, but they certainly don't spread like you describe in the Central Valley. No way they would out compete a blueberry bush. However, in small commercial farms (and what I've done at home is) use "black plastic mulch". Google it if you're unfamiliar. You might have driven by a field out in the country using it and didn't even know why they do that, or that you can do that at home. It's not what you might think of when you think of mulch. We use it to suppress weeds (that out compete the strawberries!), to keep the soil warm and moist during early months/initial planting and it keeps the fruit from contact with the ground so it doesn't get dirty and become more susceptible to surface pests and rotting.
Might it also work for keeping them from spreading where you live? I don't really know for sure, but it could be worth a shot.
On to some more general thoughts for everyone here...
In smaller spaces you can always go with a strawberry planter, or a cheap fabric hanging shoe rack on the fence. Both are much more forgiving than planting directly to the soil. Strawberries grown in native soils are particularly susceptible to soil nematodes and pathogens you don't usually get with potted mix methods, so always be aware of that as a potential issue with a failed crop. The past half century the strawberry industry has experienced a lot of controversy over how to handle that absent toxic soil fumigants. An Internet rabbit hole for you, if you're unfamiliar, and beyond the scope of this thread or post.
Another interesting fact is, the very sweetest strawberries in CA are not the commercial ones you see in the store that are grown along the coast. The small (mostly Hmong) strawberry stands in the Central Valley grow a particular variety suited for the warmer, drier conditions here. The problem is, they're pretty delicate and don't ship well so it's a local treat that you have to be here late March through early June to appreciate. It overlaps with out sweet corn season, and for many it's a time of year that everyone looks forward to. Always makes the news when those stands open up, and close for the season.
But my real point to that is, when I grow strawberries here I always grow using seeds from those berries. If you have locally grown berries (or anything else, really) you buy and like, save some seed and see if you get better results. Much of what you usually have available at your big box stores and even local nurseries at times, is grown at commercial production nurseries far away from the USDA Zone among other unique needs/stressors where you live. If it works for the guy or gal at your local farmer's market, for example, fair chance the seed from what you buy will work for you. Food for thought. And yes, that was a pun. ;)
