+1 yup my Centmin Mod wordpress auto installer installs autoptimize by default with optional end user selectable Autoptimize Gzip companion plugin of mine which automatically precompresses Autoptimize’d css/js via gzip and brotli compression if you have php brotli extension https://community.centminmod.com/threads/my-first-wordpress-autoptimize-gzip-companion-plugin.15314/ 
Mad performance combined with Centmin Mod Nginx which by default enables gzip_static and brotli_static (if brotli nginx module is enabled) so you can allow Nginx to serve pre-compressed gzip or brotli css/js optimised files - which can be up to 20-40x times faster
WebP Express plugin looks good too - early development so going through alot of versions still but looking to optionally add it as a selectable choice for my Centmin Mod wordpress autoinstaller https://community.centminmod.com/threads/installing-webp-express-wordpress-plugin-on-centmin-mod-nginx.17469/
