The dealer is probably trying to sell you a flush on each.
I would recommend a drain and refill of the transmission every 30k miles and it should not cost more than an oil change. It only uses about 2.5 qts of ATF instead of 12 with a flush and that is enough to refresh the ATF. Do that at the dealer or an independent that you trust to use only Honda ATF.
The brake fluid should be flushed and bleed when you have new brake pads done. Brake jobs are expensive but adding a flush and bleed at this time is well worth the extra money.
