All the types, airline and business, that are approved for LCY are listed on their website.

Many moons ago I was doing a feasibility study to launch a 2hr long commercial route into LCY with F70. We have found that the key limiting factor was wet runway takeoff, V1 was so low that with the required fuel load the remaining payload would have been limited to 25-30 pax on rainy days, which effectively killed the project. Interestingly another operator just recently launched the same route with E95.
Well Austrian did run a route of this length from Vienna for quite some time with the F70.
The E95 is not approved for LCY, only the E90. The same applies with the E75/E70. Reason is the slightly extended 75/95 versions are longer behind the main gear, which is an issue for tailstrikes when flaring on landing with the particular characteristics of the steep approach. Not by much but it becomes relevant.
For all that there's concern about the short TORA aircraft are commonly airborne well before the halfway point. Must be fun ...
