Your mechanic is absolutely right.

For 2004 model Corolla, I would sincerely suggest to avoid using engine flush.

cat cleaner,

For Catalytic Converter cleaning, you can use Liqui Moly Catalytic Converter cleaner.

injector cleaner

For injectors cleaning, its best to have the common rail which supplies fuel to the injectors to be removed, injectors taken out, and cleaned one by one. Liqui Moly injectors cleaner may be avoided, however, physical cleaning of injectors may only be carried out by some sensible and reliable mechanic.

Confused with mix replies? Well in my humble opinion there are a few generic rules
1. There is no substitute to opening a component and cleaning it up. Had these products been effective in recovering a choked radiator catalytic converter or injector the mech would have closed their shops. Yes these products mildly improve the sys only for a short duration. Like i used injector cleaner once in my city, it mildly improved pick but on next refill the car was back to its old pick and i was bot ready to buy another canister and pour it in fuel tank so i left it as it is
2. Whether the milage is tempered or not, if the engine is behaving the way it should you should not experiment with these products ; just for the sake of it
3. Most of the guys who used engine flush on a high milage engine had a very bad experience, so plz stay away from engine flush

Which car do you own? Make, model, model year? etc.

I sm going for catalytic converter cleaning

I think the issue which you have mentioned is related with the transmission, and not the Catalytic Converter.

First have your car's transmission sorted out.
