It is true that parquet takes longer to warm up than tiles. However, it also retains heat longer - so you could theoretically turn the heating down earlier than with tiles because the parquet does not cool down as quickly.
Have you asked the parquet installer about solid parquet? It is often not more expensive either.

Have you asked the parquet installer about solid wood parquet? That is often not more expensive.
That is not quite correct. Wood, including parquet, is a poor heat conductor and also a poor heat storage material. If you turn it down, the surface cools faster than stone. The best heat conductors are tiles. They also retain heat longer, see soapstone stoves.
Whether the parquet is suitable for underfloor heating is stated on the individual products. The installation method (gluing) is also specified in the product properties.
In all physical and heating-related matters, a completely false statement ...
Basically, it is not a problem, but slightly higher flow temperatures are required, which leads to higher consumption. However, this is not something one really needs to worry about.
