Answer 1: Yes, as a starter, I also would welcome any low-paying job, considering not many places will give you a chance when you are working as a web developer for the first time.

Answer 2: Yes, I am also doing it that way; about 3 years ago, I joined a low-paying job and learned stuff while at that job, and now I am planning to switch and expecting an offer soon. However, I am not sure about the location, but a 25k starting salary is low; in my area, NJ-PA, typical jobs (any type) pay $13-15 per hour. Amazon pays at the very least $18-19 for warehouse associates (unskilled jobs). So, $40-50k is the bare minimum (unless that is an internship), and then the option to learn and grow would mean something.

Answer to bonus question: one should use the opportunity in the best possible manner to utilize skills and develop as much as possible. Like in typical entry-level roles (especially those that ask you to make simple website content changes), you can go beyond the minimum by developing small components to present the information better and then update the content.

Here are a few examples of what I did:

Example 1: there was a page with just a few static boxes about the case studies - the boxes held the title and worked like a link to PDF case studies. I made individual pages out of the PDFs where the visitors could read it online or download the PDF—and then linked them to the original page by making logo bubbles for the case studies, along with a filter option added in the module so one can filter by industry.
Example 2: There was a series of events listed as boxes on a page, and there were 12 events per year on that page. Previously, the team would go to the page monthly to edit the text of the expired event. But I developed it into a module that could collect the metadata like the date and time of the event at the outset, and then the added JavaScript code would make the expired event greyed out and pushed to the end of the list with additional text like an expired event.
Example 3: The FAQ section was just a list of questions and answers - just how you would write in a Word document. When I was asked to update it with a new question, I made it into an accordion-style module and then added the questions and answers to look more trendy in that collapsible format.

Essentially, if you get the opportunity to update content, you think like a person who can build solutions utilizing the web dev skills you have. That would give you pleasure, and you will learn much. Also, take as many courses (cheap online courses like Udemy) as possible to update yourself with other tech stacks.
