the OP is asking for advice on the easiest approval method. Soft power applications such as with Muay Thai documents appear to be more straight forward and less likely to be asked for additional documents provided from a credible legitimate source. There are less variables open to interpretation.
Also there is nothing in the future to prevent using DTV for the workcation route or vice versa from what I understand once DTV is approved. This is another reason why this visa is a fantastic option for many.
Anonymous participant so you're applying via soft power - music festival or just asking online about this option, less than 24 hour before you apply 🤔?
A consulate would never approve a passport that has already expired. Even if you did enter this incorrect past date then visa should not be processed. Unlikely to be an issue entering the Kingdom but better to contact the consulate to advise them so you have it on record - sooner the better.
