Audio Advice on audio export options for large number of audio clips

I have ~1000 audio clips that are 1-3 seconds long that are frequently played in-game. The game will be exported to android and iOS.

The goal is to reduce size, have great sound quality, and run well on low-end devices. What export options should I be using? Currently I'm using audacity and exporting wav files to mp3, with variable bit rate, variable speed - fast, mono export. The audio files are mono, 44100Hz 32-bit floats. Also trimming all silence at the beginning and end with no padding.

Within unity, force to mono - enabled, normalize - enabled, load in background and ambisonic - disabled, the load type is decompress on load, preload audio data enabled, compression format - vorbis, quality - 100, sample rate setting - preserve sample rate.

Are these good settings to have for a massive amount of short audio clips that are played frequently, or should I change something?
