I know and understand what was the experience of Nicole.
Near two years ago I will try to move my works on Linux ... it ws a disaster.
On new PC two desktop with I9-14900K and two notebook I9-14900HX Linux (I tried Ubuntu and Mint ... don't remember what versions) nothing worked.
Desktop PC were assembled by me, and Linux was installed in real machine alone, UEFI disabled. Same in notebooks, after changed the orginal manufactored SSD.
Bluethoot mouse was not recognized, graphic cards sometimes worked, somtimes don't. The i9 processors never worked well, hardware ITD support in Linux was not operational at that time.
The same touch screen monitor (HDPI) didn't work well (instead of 10 touch points may be no more than two worked ... and also the resolution and some Linux software was not working well with lot of issues). I worked at that time with X11 and Wayland to test.
I don't remmeber if Linux was under systemd or old init.
All PC were with 32 GB of RAM.
Come with Lazarus: installed from repository (apt) the versions was 1.6 ( :'( ) and 2.0.6 ... at that time there were 3.2 stable release (if I remember right). I created a copy of official repo (SF) and a bash script to install 3.2 version.
Naturally, I abandoned the experiment and shelved the matter. Never tried Linux in a real machine anymore. In Windows NEVER and NEVER had issues like those ... I repeat NEVER in my life.
So, I understand Nicole.
My experience is unique, may be yes and sure is not to take as example.
I understand your situation and Nicole's. And I respect both of your choices.
It's unlikely that on the first day you turned on a computer, or used Microsoft Windows, or used Microsoft Office, or used any database or any programming language without attending any school or course, you managed easily without experiencing any difficulties. Even if you don't remember now that many years have passed, there were indeed difficulties and a learning curve. The same applies to Linux or any other professional change you might want to make.
Using Microsoft Windows seems easy because you've been doing it for many years, every day. After many years of using Linux, you'll also have that feeling of ease and belonging. This applies to everything in life.
Ease, time, and money are intertwined variables.
Every change has a natural learning curve, which may require effort, time, and money.
Learn to walk before you want to run.
Although I try to help within my limits, choices and consequences are always individual.
My suggestion remains:
- Learn to walk before you want to run;
- If you're not in a hurry, it's cheap;
- If you invest money, it's fast;
- You decide on your effort, time, and money: there's no such thing as a free lunch;
- Always remember the learning curve: be patient and persevering;
- Take some courses on Linux, whether paid or free. YouTube videos are also fine;
- Remember that it takes time, study, and practice to learn something new;
- Prepare some hardware (virtual machine, or USB drive, or new or used computer).
- Choose a few Linux distributions to test. This is like dating before marriage;
- After testing, choose a Linux distribution to call your own. This is like a marriage, including joys and sorrows, with the risk and possibility of divorce and remarriage too

- Regarding Firebird on Linux, there is a lot of help both in the Firebird groups themselves and here in this forum;
- Regarding TurboBird or FlameRobin on Linux, there is help both in the Firebird groups themselves and here in this forum;
- Regarding Free Pascal and Lazarus on Linux, there is a lot of help here in this forum;
- In the end, you decide the pace of effort needed to achieve your goal. Don't get discouraged.
