If you don’t have access, you can either run a client on a different server using DNS verification or use one of the in-browser clients (such as ZeroSSL). As for the key length, normally 4096 is considered to be a “safer” and more future-proof bet, but in some cases you need to use 2048 (for example for AWS CloudFront, some specifc networking devices, etc).
