It looks like your siding is beginning to buckle. I'd be careful about putting vining plants there as they might get up under the siding. That would be a real mess. I know a lot of people are anti-forsythia, but it would love this spot. You can let it get tall without worrying about damage to the siding. Plus, it will create a bit of a shade canopy that you would underplant with more colorful things once the forsythia leafs out.
