Application form for lecturer position provides a template for an academic resume, should I follow that?

There is nothing in the statement ``(an Academic CV template is available here)'' indicating this is a required format. I would assume that most applicants would not use the template.

I suspect the template is there to help applicants. Does it have a place for hobbies? If not, probably you want to not list hobbies. It does have a place for ``contributions to the university'' so be sure it is clear on your CV if you ever sat on a campus-wide committee or some such thing. Different cultures put in different things in a CV, but in this case you have a guide.

The fact that the template has separate sections for different types of service makes me suspect this is a generic format used for scholars at many ranks and many departments. There may be many sections any specific person would have blank.

I suspect that most of the applicants will use the template. I also suspect that the search committee will expect all applicants' CVs to be in the same order.

If it were I, I'd use the template, omit entirely the things that aren't applicable in your case, and very briefly address those in a cover letter.

Re-formatting the application pack for each vacancy is a huge waste of time. Some parts of it, such as the cover letter, may need to be adjusted to match the requirements of the vacancy. Other parts, such as CV, Publication List, Research statement, Teaching statement, etc, reflect your current profile. A University which asks these documents to be re-formatted for them is putting a huge additional burden on applicants. This is largely a test in compliance with bureaucratic requirements, than a test of your academic skills and abilities. It's up to you to decide whether the job is worth participating in such a test.

Outside academia, e.g. in IT sector, companies are searching for the candidates based on their online profiles, e.g. LinkedIn. All necessary details are clarified via interviews over the phone, skype/zoom or in person. Companies which expect developers to re-format CVs for them will likely go bust very quickly.
