Can Electrolytic SMD be used in place of 1210 mlcc SMD ?

[ThomsCircuit]

I have been working on and manipulating this project. Increasing pour pad sizes and adding heat sinks under the inductors. I know it is cheaper to purchase it but this is for learning. I came across an article where a similar buck /boost was being designed but the author used Electrolytic instead on mlcc caps. He claimed the project worked better. Now while I would like to use what is listed for my project I don't have 22uf 35V or 47uf 25v in a 1210 package but I do have them in 1206. I also have them in Electrolytic. So could I use these substitutes or would it be better locate the 1210 mlcc type?
The location of the 1210 mlcc's on the PCB is C1, 2, 5, and 7

Use higher voltage & higher ripple current rated ones, in the larger package.

Higher ratings compared to actual loads gives massively longer life.

Electrolytic capacitors will generally have a higher ESR than ceramic ones, and in a switch-mode supply, ESR is probably the most important parameter.

Electrolytic capacitors age with time and heat, and the ESR can make them heat up with high ripple currents.

The capacitance of ceramic capacitors (other than COG ones) reduces as the voltage on them increases. At their rated voltage the capacitance will often be a lot less, maybe only 30% or so of the rated capacitance. Having physically larger ones often reduces this effect. However the ESR is usually what makes most difference so the reduction in capacitance may not be important.

Ceramic capacitors can crack if there is any flexing of the board.
