Agree you can only go lighter with peroxide/ bleach - honey is a very mild source of peroxide, box dyes also contain peroxide. In and of itself lightening from dark blonde to honey blonde should not be that damaging because it's only a few shades.
The problem comes when the damage is compounded, hair down at your waist may have little to no cuticle left simply through the passage of time, hair that is straightened either by heat or chemicals will also be damaged, if you intend to have more streaks later to hit your roots there is every chance some of the hair will get double processed.
I highly recommend you buy a 'sacrificial' blonde box dye and do strand tests on shed hair to see what colour you might expect and how damaged the hair becomes. When you have the hair lightened, flat iron it a good few times, if indeed that is how you currently straighten, then see how strong it is. You may not go strawberry blonde, you may not have much red undertones in your hair, many dirty blondes do not we are cool/ ashy/ mousey.
The least damaging way of lifting is to bleach over coconut oil soaked hair. This is actually beneficial for any damaged or porous hair but may not absorb if your hair is coated in silicones.
