I modded my almost new dumb oven (2 knobs and indicator light) with cast iron plates about 5 millimeters thick on top and bottom, with some additional rails to quickly remove them if necessary. The heat up process is a bit slower, but overall the oven performs way better than stock one and bakes evenly.
This is thermal mass right over heaters for even roasting/baking.
If I want crust, I just pop on the ventilator in the oven for 10 minutes before done, perfect every time.
As for bread, i pop out the plates, Heat the oven and cast iron pot with lid to 260C, pop in the bread when hot and forget about it for 45 minutes.
If he wants Tech in the oven, well let's see his ideas. At friends house they bought new $INSERT_NAME oven (overpriced around 1500€) with all the bells all over, you can't even expect to turn it on without at least reading 10 pages of the 80 pages long manual. It's super energy saving design takes like 20 minutes to heat up to 200C or ~30 minutes to 250C. For the fun of it we popped in an NTC sensor to see what's going on in heat up and baking process. Nice SLOOOW and steady heat up, then we popped in a roast. Temperature dropped around 40C then heating back up for 16 minutes, overshoot set temperature by 18C, dropped back 21C under set temp and oscillated all the way to the end. All the micro controlling in there failed with REGULAR use.
With that price tag you expect at least steady even temperature, but noooo, $INSERT_NAME decided to screw the customer with poor excuse for an oven, and telling you that you baked your stuff wrong all your life, so they decided to set you straight.
If I wanted to die of waiting I would go to DMV line...
