To my knowledge, the latest non-alpha version of the @ui5/cli and @sap/ux-ui5-tooling (as of 2nd March 2022 - version 2.14.6 and 1.5.0 respectively) are the ones to use.
However, I wanted to confirm as my organisation has multiple ui5 projects and so having a standardised version of the @ui5/cli and @sap/ux-ui5-tooling dependencies could prevent issues around bugs in tooling.
If the advice is just to use the latest non-alpha version, then I just need to update the dependencies regularly.
The versions you mentioned should be your choice to use in a productive environment.
The upcoming UI5 tooling 3.0 is not.
