I have cracked probably 20 BGS/SCD holders that are tougher and 10 SGC holders that are really easy. Haven't done a BCCG one, but they're probably easier than BGS standard holders. SGC you can pry open with a butter knife along the edge. For BGS/SCD, I use pliers to snap off a corner by torquing it, then pry open with a flathead screwdriver. Only slightly bent one card out of the 30 or so I've cracked.
PSA will do it just fine if you submit as a crossover and set whatever minimum grade you'd require. As to grade you should expect, you should know how the grades look and compare to the current listed standards on the PSA website. A BCCG 9 could theoretically grade anywhere between a 6 to even a 9, possibly. Not sure how they grade for centering on BCCG, but BGS centering subgrades are tougher than the PSA grade requires. So you can take BGS 9s if you know what to look for and they'll normally cross to PSA 10 as long as the corners are sharp.
