To determine the transfer function of such op-amp-based circuit, it is easy to apply the fast analytical circuits techniques or FACTs. The exercise is quite simple: determine the natural time constants of this circuit when the source (\$V_{in}\$) is reduced to 0 V or replaced by a short circuit in the electrical diagram. To determine time constants, simply "look" at the resistance offered by \$C_1\$ and \$C_2\$ connecting terminals when they are temporarily disconnected from the circuit. This will give you \$\tau_1\$ and \$\tau_2\$. Summing them leads to the first term \$b_1=\tau_1+\tau_2\$. The second high-frequency term \$b_2\$ is obtained by combining \$\tau_2\$ and another term \$\tau_{21}\$. This second term implies that capacitor \$C_2\$ is set in its high-frequency state (a short circuit) while you determine the resistance offered by \$C_1\$ connecting terminals. You finally assemble the terms as follows:
\$D(s)=1+sb_1+s^2b_2=1+s(\tau_1+\tau_2)+s^2\tau_2\tau_{21}\$.
The below sketch shows you the way. Start with \$s=0\$ and open all caps. The gain in this mode is 1: no leading term for the final transfer function. Then proceed by determining the time constants. Once it is done, you have your transfer function without writing a single line of algebra!

You can capture your formulae in a Mathcad sheet and rearrange it to express the final result in a low-entropy format: a quality factor \$Q\$ (or a damping ratio if you like it) and a resonant angular frequency \$\omega_0\$. It is easy to do because the FACTs naturally lead you to a formalized denominator form with \$b_1\$ and \$b_2\$. This is the correct way to express a transfer function.

The FACTs are not only faster than any other methods but they naturally deliver a clear and ordered form fitting the low-entropy format. This format is necessary to let you design your circuit so that you meet some of the desired criteria: quality factor and resonant frequency. Furthermore, for simple circuits like this one, you can determine the transfer function by inspection, without writing a line of algebra. Should you make a mistake, simply solve one of the intermediate sketches without restarting from scratch. A truly powerful skill that I encourage students and EEs to acquire: once you master it, you won't return to classical analysis.
